THz range Faraday rotation in the Weyl Semimetal Candidate
Rishi Bhandia, Bing Cheng, Tobias Brown-Heft +3
The family of ferromagnetic Heusler alloys have attracted interest due to their fully spin-polarized nature, making them ideal for applications in spintronic device…
A Large Effective Phonon Magnetic Moment in a Dirac Semimetal
Bing Cheng, T. Schumann, Y. C. Wang +4
We investigated the magnetoterahertz response of the Dirac semimetal CdAs and observed a particularly low frequency optical phonon, as well as a very prominent and field se…
Magnetoterahertz Response and Faraday Rotation from Massive Dirac Fermions in the Topological Crystalline Insulator PbSnTe
Bing Cheng, P. Taylor, P. Folkes +2
PbSnTe has been shown to be an interesting tunable topological crystalline insulator system. We present a magneto-terahertz spectroscopic study of thin films of Pb$_{0.…
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…
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…
