Optimizing defect states in ternary topological insulators using indium doping
Kanav Sharma, Ritam Banerjee, Anuvab Nandi +2
This study investigates the influence of indium doping on the defect states in (Bi0.3Sb0.7)2Te3 (BST) ternary topological insulators. Thin (10 nm) and thick (60 nm) films of pristi…
Investigation of magnetic order influenced phonon and electron dynamics in MnBiTe and Sb doped MnBiTe through terahertz time-domain spectroscopy
Soumya Mukherjee, Anjan Kumar NM, Subhadip Manna +4
MnBiTe, the first topological insulator with inherent magnetic ordering, has attracted significant attention recently for providing a platform to realize several exotic…
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…
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…
