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…
Optimizing Pulsed Optically Detected Magnetic Resonance Acquisition: A Digital Signal Processing Perspective
Anuvab Nandi, Sayan Chakraborty, Yashvardhan Jain +6
Ensembles of nitrogen vacancy (NV) defect centers in diamond have attracted considerable interest for fundamental studies and applications in quantum sensing and quantum informatio…
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…
Enhancement of spin to charge conversion efficiency at the topological surface state by inserting normal metal spacer layer in the topological insulator based heterostructure
Sayani Pal, Anuvab Nandi, Shambhu G. Nath +5
We report efficient spin to charge conversion (SCC) in the topological insulator (TI) based heterostructure () by using spin-pumping techniq…
