Measurement of the topological surface state optical conductance in bulk-insulating Sn-doped BiSbTeS single crystals
Bing Cheng, Liang Wu, S. K. Kushwaha +2
Topological surface states have been extensively observed via optics in thin films of topological insulators. However, in typical thick single crystals of these materials, bulk sta…

A Modified Geometry With Reduced Optical Aberrations For Improved Time Domain Terahertz Spectroscopy
N. J. Laurita, Bing Cheng, R. Barkhouser +2
We present a modified geometry for time domain terahertz (THz) spectroscopy (TDTS) experiments. We show, through simulations and data, that a simple rearranging of the off-axi…

Tuning and Stabilizing Topological Insulator Bi2Se3 in the Intrinsic Regime by Charge Extraction with Organic Overlayers
Liang Wu, R. M. Ireland, M. Salehi +5
In this work, we use charge extraction via organic overlayer deposition to lower the chemical potential of topological insulator Bi2Se3 thin films into the intrinsic (bulk-insulati…
