Terahertz Spectroscopy of Topological Insulators and other 2-Dimensional Materials
… two classes of Dirac materials - graphene 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, …

MICROWAVE STUDY OF THE PROPERTIES OF UNCONVENTIONAL SUPERCONDUCTING SYSTEMS
… superconductor, a signature of Andreev bound states was also found. A phenomenological model to explain the observed properties of the Andreev bound states is also discussed. Lastly, an effort to broaden the adaptability of the new technique to samples of more general morphology is discussed. …

Topological Insulators Interfaced with Trivial and Ferromagnetic Insulators. Selective contact and patterning of surface states.
Topological insulators (TIs) are a novel class of material which host helical surface states with exciting and unique electronic properties. They can provide insights into new physics and also pave the way for potential spintronic applications. Much work has been done to identify and characterise …
