Optical investigation of bismuth selenide (Bi2Se3) and antimony telluride (Sb2Te3).
… properties of two topological insulators, Bismuth Selenide (Bi2Se3) and Antimony Telluride (Sb2Te3), by optical spectroscopy reflection measurements in a wide frequency range (500 – 40000 cm−1 ) and temperature (13 to 300 K) . Utilizing Kramers-Kronig analysis, complex conductivity is …

Terahertz Spectroscopy of Topological Insulators and other 2-Dimensional Materials
… and topological insulators (TIs) namely, bismuth selenide (Bi2Se3) and antimony telluride (Sb2Te3). Specifically, we investigate the optical behavior of Dirac materials using terahertz time domain spectroscopy (THz-TDS) contact-free optical technique, used to probe the low-energy …

The superconducting proximity effect in Bi2Se3 thin-films
… devices. In this work, the topological insulator Bi2Se3, which supports special metallic surface states as a consequence of the topology of its bulk bands, is tiled with micron-scale islands of the superconductor niobium. The superconducting islands interact with the Bi2Se3 and each other through …
