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.…
Tuning Chemical Potential in the Dirac Cone by Compositional Engineering
R. K. Gopal, Sourabh Singh, Jit Sarkar +1
We report the successful formation of bulk insulating ternary topological insulators candidate Bi2Se2Te (BST) by pulsed laser deposition technique. The films were deposited with se…
