Observation of excess resistance anomaly at resistive transitions in Ag/Au nanostructures
Phanibhusan S Mahapatra, Subham Kumar Saha, Rekha Mahadevu +8
The resistive transition in nanocomposite films of silver (Ag) nanoclusters of ~ 1 nm diameter embedded in gold (Au) matrix exhibits an anomalous resistance peak at the onset of th…
Mis-orientation controlled cross-plane thermoelectricity in twisted bilayer graphene
Phanibhusan S Mahapatra, Bhaskar Ghawri, Kenji Watanabe +3
The introduction of 'twist' or relative rotation between two atomically thin van der Waals (vdW) membranes gives rise to periodic Moire potential, leading to a substantial altercat…
Atomically-Smooth Single-Crystalline VO thin films with Bulk-like Metal-Insulator Transitions
Debasish Mondal, Smruti Rekha Mahapatra, Tanweer Ahmed +3
Atomically-abrupt interfaces in transition metal oxide (TMO) heterostructures could host a variety of exotic condensed matter phases that may not be found in the bulk materials at…
Current-voltage characteristics in Ag/Au nanostructures at resistive transitions
Saurav Islam, Rekha Mahadevu, Subham Kumar Saha +7
Transitions to immeasurably small electrical resistance in thin films of Ag/Au nanostructure-based films have generated significant interest because such transitions can occur even…
Low temperature saturation of phase coherence length in topological insulators
Saurav Islam, Semonti Bhattacharyya, Hariharan Nhalil +7
Implementing topological insulators as elementary units in quantum technologies requires a comprehensive understanding of the dephasing mechanisms governing the surface carriers in…
Signature of pseudo-diffusive transport in mesoscopic topological insulators
Saurav Islam, Semonti Bhattacharyya, Hariharan Nhalil +2
One of the unique features of Dirac Fermions is pseudo-diffusive transport by evanescent modes at low Fermi energies when the disorder is low. At higher Fermi energies i.e. carrier…
