Linear magnetoresistance and surface to bulk coupling in topological insulator thin films
Sourabh Singh, R. K. Gopal, Jit Sarkar +3
We explore the temperature dependent magnetoresistance of bulk insulating topological insulator thin films. Thin films of Bi2Se2Te and BiSbTeSe1.6 were grown using Pulsed Laser Dep…
Bulk Saturable absorption in Topological Insulator thin Films
Radha Krishna Gopal, Deepak K. S. Ambast, Sourabh Singh +3
We present nonlinear optical absorption properties of pulsed laser deposited thin films of topological insulator (TI), Bi2Se3 on quartz substrate, using open aperture Z - scan tech…
Parallel and series conduction model in Topological Insulators
Sourabh Singh, R K Gopal, Jit Sarkar +1
In the past few years there has been a surge in the material science engineering in order to synthesize bulk insulating and surface metallic Topological Insulating (TI) materials.…
Topological delocalization and tuning of surface channel separation in Bi2Se2Te Topological Insulator Thin films
R. K. Gopal, Sourabh Singh, Arpita Mandal +2
The surface states of a 3D topological insulator (TI) exhibit topological protection against backscattering. However, the contribution of bulk electrons to the transport data is an…
