It is important to ensure the near field geometry used does not introduce spectral artifacts. For example, many scanning techniques can be strongly influenced by the interaction between the scattering tip and the sample. Here we examine the spectroscopic effects of a 200 μm diameter aperture for THz near-field measurements. We use HFSS to model free-space transmission through samples with resonant absorbance as a function of sample thickness, lateral sample width, and aperture diameter. We examine the transmitted power and spectral fidelity for coupling of transmitted THz light onto a detector. These studies inform corrective post-measurement analysis algorithms and design of near-field detection systems.&lt;/div&gt;

At low frequencies, transport is essentially thickness independent showing the dominant contribution of the surface electrons. Despite their extended exposure to ambient conditions, these surfaces exhibit robust properties including narrow, almost thickness-independent Drude peaks, and an unprecedentedly large polarization rotation of linearly polarized light reflected in an applied magnetic field. This Kerr rotation can be as large as 65 degrees and can be explained by a cyclotron resonance effect of the surface states.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000300576000025</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: 896NY&lt;br/&gt;Times Cited: 164&lt;br/&gt;Cited Reference Count: 35&lt;br/&gt;Cited References: &lt;br/&gt;     Akhmerov AR, 2009, PHYS REV LETT, V102, DOI 10.1103/PhysRevLett.102.216404&lt;br/&gt;     Alpichshev Z, 2010, PHYS REV LETT, V104, DOI 10.1103/PhysRevLett.104.016401&lt;br/&gt;     Analytis JG, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.205407&lt;br/&gt;     Bansal N., ARXIV11045709&lt;br/&gt;     Benia HM, 2011, PHYS REV LETT, V107, DOI 10.1103/PhysRevLett.107.177602&lt;br/&gt;     Bianchi M, 2010, NAT COMMUN, V1, DOI 10.1038/ncomms1131&lt;br/&gt;     Butch NP, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.241301&lt;br/&gt;     Chen J, 2011, PHYS REV B, V83, DOI 10.1103/PhysRevB.83.241304&lt;br/&gt;     Chen YL, 2009, SCIENCE, V325, P178, DOI 10.1126/science.1173034&lt;br/&gt;     Essin AM, 2009, PHYS REV LETT, V102, DOI 10.1103/PhysRevLett.102.146805&lt;br/&gt;     Eto K, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.195309&lt;br/&gt;     Fu L, 2007, PHYS REV B, V76, DOI 10.1103/PhysRevB.76.045302&lt;br/&gt;     Fu L, 2008, PHYS REV LETT, V100, DOI 10.1103/PhysRevLett.100.096407&lt;br/&gt;     Hsieh D, 2008, NATURE, V452, P970, DOI 10.1038/nature06843&lt;br/&gt;     Hsieh D, 2009, NATURE, V460, P1101, DOI 10.1038/nature08234&lt;br/&gt;     Jenkins GS, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.125120&lt;br/&gt;     King PDC, 2011, PHYS REV LETT, V107, DOI 10.1103/PhysRevLett.107.096802&lt;br/&gt;     LaForge AD, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.125120&lt;br/&gt;     Lan YP, 2011, PHYS REV B, V83, DOI 10.1103/PhysRevB.83.205109&lt;br/&gt;     Maciejko J, 2010, PHYS REV LETT, V105, DOI 10.1103/PhysRevLett.105.166803&lt;br/&gt;     Moore JE, 2007, PHYS REV B, V75, DOI 10.1103/PhysRevB.75.121306&lt;br/&gt;     Qi XL, 2008, PHYS REV B, V78, DOI 10.1103/PhysRevB.78.195424&lt;br/&gt;     Qu DX, 2010, SCIENCE, V329, P821, DOI 10.1126/science.1189792&lt;br/&gt;     Roushan P, 2009, NATURE, V460, P1106, DOI 10.1038/nature08308&lt;br/&gt;     Roy R, 2009, PHYS REV B, V79, DOI 10.1103/PhysRevB.79.195322&lt;br/&gt;     Steinberg H, 2011, PHYS REV B, V84, DOI 10.1103/PhysRevB.84.233101&lt;br/&gt;     Sushkov AB, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.125110&lt;br/&gt;     THOULESS DJ, 1982, PHYS REV LETT, V49, P405, DOI 10.1103/PhysRevLett.49.405&lt;br/&gt;     Tkachov G, 2011, PHYS REV B, V84, DOI 10.1103/PhysRevB.84.035405&lt;br/&gt;     Tse WK, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.161104&lt;br/&gt;     Tse WK, 2010, PHYS REV LETT, V105, DOI 10.1103/PhysRevLett.105.057401&lt;br/&gt;     VONKLITZING K, 1980, PHYS REV LETT, V45, P494, DOI 10.1103/physrevlett.45.494&lt;br/&gt;     Xia Y, 2009, NAT PHYS, V5, P398, DOI 10.1038/NPHYS1274&lt;br/&gt;     Xiong J., PHYSICA A E IN PRESS&lt;br/&gt;     Zhang XA, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.245107&lt;br/&gt;Aguilar, R.

We show that this photoresponse does not arise from a heating effect, but that it is instead excellently described by a classical model of terahertz-induced gate-voltage rectification. This effect is distinct from the rectification mechanisms that have been studied previously, being determined by the phase-dependent interference of the source drain and gate voltage modulations induced by the terahertz field.

From this work, we found that the nature of the vibrational motions activated by terahertz radiation is surprisingly similar between these two structurally similar proteins. Specifically, at the lowest frequencies probed, the cytoplasmic loop regions of the proteins are highly active; and at the higher terahertz frequencies studied, the extracellular loop regions of the protein systems become vibrationally activated. In the case of bacteriorhodopsin, the calculated terahertz spectra are compared with the experimental terahertz signature. This work illustrates the importance of terahertz spectroscopy to identify vibrational degrees of freedom which correlate to known conformational changes in these proteins.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000254420100030</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: 280IP&lt;br/&gt;Times Cited: 50&lt;br/&gt;Cited Reference Count: 72&lt;br/&gt;Cited References: &lt;br/&gt;     Abdulaev NG, 1998, P NATL ACAD SCI USA, V95, P12854, DOI 10.1073/pnas.95.22.12854&lt;br/&gt;     Alexandrov V, 2005, PROTEIN SCI, V14, P633, DOI 10.1110/ps.04882105&lt;br/&gt;     Alexiev U, 2003, J MOL BIOL, V328, P705, DOI 10.1016/S0022-2836(03)00326-7&lt;br/&gt;     Altenbach C, 2001, BIOCHEMISTRY-US, V40, P15493, DOI 10.1021/bi011545o&lt;br/&gt;     AMADEI A, 1993, PROTEINS, V17, P412, DOI 10.1002/prot.340170408&lt;br/&gt;     Balog E, 2004, PHYS REV LETT, V93, DOI 10.1103/PhysRevLett.93.028103&lt;br/&gt;     Beck M, 1998, BIOCHEMISTRY-US, V37, P7630, DOI 10.1021/bi9801560&lt;br/&gt;     Bizzarri AR, 2001, EUR BIOPHYS J BIOPHY, V30, P443, DOI 10.1007/s002490100167&lt;br/&gt;     BROOKS B, 1983, P NATL ACAD SCI-BIOL, V80, P6571, DOI 10.1073/pnas.80.21.6571&lt;br/&gt;     BROOKS BR, 1995, J COMPUT CHEM, V16, P1522, DOI 10.1002/jcc.540161209&lt;br/&gt;     Bu ZM, 2000, J MOL BIOL, V301, P525, DOI 10.1006/jmbi.2000.3978&lt;br/&gt;     Chen JY, 2005, PHYS REV E, V72, DOI 10.1103/PhysRevE.72.040901&lt;br/&gt;     Chen Q, 2001, J OPT SOC AM B, V18, P823, DOI 10.1364/JOSAB.18.000823&lt;br/&gt;     Chung HS, 2005, P NATL ACAD SCI USA, V102, P612, DOI 10.1073/pnas.0408646102&lt;br/&gt;     Crozier PS, 2003, J MOL BIOL, V333, P493, DOI 10.1016/j.jmb.2003.08.045&lt;br/&gt;     Farrens DL, 1996, SCIENCE, V274, P768, DOI 10.1126/science.274.5288.768&lt;br/&gt;     Filippovich S.

Measurements were performed using terahertz time domain spectroscopy on aqueous solutions below the liquid-solid transition for water. Small ligand binding sensitivity was demonstrated using triacetylglucosamine and hen egg white lysozyme with a decrease in dielectric response with binding. The magnitude of the change increases with frequency.

Determining the momentum relaxation time from a Drude model, the authors find a lower value than that from dc measurements, particularly at high frequencies/low temperatures. These deviations are consistent with the ratio tau(t)/tau(q,) where tau(q) is the full scattering time. This suggests that small-angle scattering leads to weaker heating of 2DEGs at low temperatures than expected from dc mobilit9y.

Previously we have shown a strong contrast between the THz dielectric response for wild type (WT) and D96N mutant of bacteriorhodopsin. In those studies we observed a large increase in the THz absorbance of WT with excitation to thermally captured photo-intermediates whereas no such increase in absorbance was observed for the mutant D96N. These results suggest that the THz response is sensitive to structural changes and relative flexibility of biomolecules. However the photo-intermediate populations of the WT and D96N samples were not equivalent in those measurements. While the WT samples had relaxed (bR), M and P state intermediates present, the D96N samples had only bR and M states. Here we present terahertz absorbance measurements of D96N as a function of M and P state populations at room temperature. The THz response is constant for intermediate states populations up to 23% M state and up to 30% P state. These results verify that there is a fundamental difference in the conformational dynamics as measured by THz dielectric response for a single residue mutation.&lt;/p&gt;&lt;/div&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Markelz, A.

The spectrally integrated THz output had a nonmonotonic temperature dependence in all cases with the value increasing by a factor of 3 from room temperature to 150 K for low biases and 100 K at high biases. An abrupt decrease in output power occurs below 90 K, and the spectrum shifts to lower frequencies as the temperature is lowered.

We find that the energy distribution can be characterized by an effective electron temperature, T-e(&amp;gt;T-L), that agrees well with values estimated from the THz-illuminated, dc conductivity. This agreement indicates that under strong THz drive, LO phonon scattering dominates both energy and momentum relaxation; that the carrier distribution maintains a heated, thermal form; and that phonon drift effects are negligible.
