Magneto-transport studies on Bi2Te2+xSe1–x (x = 0.05 and 0.10) topological insulators
Source abstract
Abstract
Bi2Te2Se is one of the most promising three dimensional topological insulators, for the study of surface states. In this work, we report the results of transport and magneto-transport behavior of Bi2Te2+xSe1–x (x=0.05 and 0.10) single crystals grown using modified Bridgeman technique. Resistance versus temperature measurements show semiconducting behavior for x = 0.05 and 0.10 crystals. Linear magnetoresistance is observed for Bi2Te2.05Se0.95 (i.e. x=0.05) whereas, Bi2Te2.10Se0.90 (x=0.10) single crystal shows a conductance fluctuations at low magnetic field.
