First principles study of bandgap tuning in GePbSe
Himanshu Lohani
Narrow bandgap and its tuning are important aspects of materials for their technological applications. In this context group IV VI semiconductors are one of the interesting candida…
Observation of Dirac-like surface state bands on the top surface of BiSe
H. Lohani, K. Majhi, R. Ganesan +5
Two quintuple layers of strong topological insulator Bi2Se3 are coupled by a Bi bilayer in BiSe crystal. We investigated its electronic structure using angle resolved photoelectron…
Band Structure of Topological Insulator BiSbTe1.25Se1.75
H. Lohani, P. Mishra, A. Banerjee +6
We present our angle resolved photoelectron spectroscopy (ARPES) and density functional theory results on quaternary topological insulator (TI) BiSbTe1.25Se1.75 (BSTS) confirming t…
Emergence of a weak topological insulator from the BiSe family and the observation of weak anti-localization
Kunjalata Majhi, Koushik Pal, Himanshu Lohani +7
The discovery of strong topological insulators led to enormous activity in condensed matter physics and the discovery of new types of topological materials. Bisumth based chalcogen…
