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…
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…
Optimising Graphene Visibility in van der Waals Heterostructures
Thanmay S. Menon, Simli Mishra, Vidhu Catherine Antony +8
Graphene constitutes one of the key elements in many functional van der Waals heterostructures. However, it has negligible optical visibility due to its monolayer nature. Here we s…
Bulk-impurity induced noise in large-area epitaxial thin films of topological insulators
Saurav Islam, Semonti Bhattacharyya, Abhinav Kandala +3
We report a detailed study on low-frequency 1/f-noise in large-area molecular-beam epitaxy grown thin (10 nm) films of topological insulators as a function of temperature, gate vol…
