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.
