Photon Momentum Enabled Symmetry Breaking and Nonlinear Photocurrents in the Centrosymmetric Dirac Semimetal PdTe
Sambhu G Nath, Subhadip Manna, R K Gopal +1
In centrosymmetric Dirac semimetals, second order nonlinear photocurrents are forbidden by the coexistence of time-reversal and inversion symmetries. Here, we demonstrate that fini…
Magnetoconductance evolution across the topological-trivial phase transition in thin films
Sambhu G Nath, Subhadip Manna, Kanav Sharma +4
We investigate the evolution of electronic transport across the topological-trivial phase transition in thin films by s…
Band Meandering due to Charged Impurity Effects and Carrier Transport in Ternary Topological Insulators
Kanav Sharma, Niranjay K R, Infan S Mesh +2
Controlling charged impurity disorder is a critical challenge for realizing the promise of topological insulator (TI) surfaces in devices. While doping is often used to tune the ch…
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…
Anisotropic magneto-photothermal voltage in Sb2Te3 topological insulator thin films
Subhadip Manna, Sambhu G Nath, Samrat Roy +8
We studied longitudinal and Hall photothermal voltages under a planar magnetic field scan in epitaxial thin films of the Topological Insulator (TI) Sb2Te3, grown using pulsed laser…
