Development of planar microstrip resonators for electron spin resonance spectroscopy
Subhadip Roy, Sagnik Saha, Jit Sarkar +1
This work focuses on the development of planar microwave resonators which are to be used in electron spin resonance spectroscopic studies. Two half wavelength microstrip resonators…
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.…
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…
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…
Surface Optical and Bulk Acoustic Phonons in the Topological Insulator, Bi2Se2Te
Uditendu Mukhopadhyay, Dipanjan Chaudhuri, Jit Sarkar +5
We explore the phonon dynamics of thin films of the topological insulator material Bi2Se2Te using ultrafast pump-probe spectroscopy. The time resolved differential reflectivity of…
