Inhomogeneous hysteresis in local STM tunnel conductance with gate-voltage in single-layer MoS on SiO
Santu Prasad Jana, Suraina Gupta, Anjan Kumar Gupta
Randomly distributed traps at the MoS/SiO interface result in non-ideal transport behavior, including hysteresis in MoS/SiO field effect transistors (FETs). Thus tr…
Superconductor to metal quantum phase transition with magnetic field in Josephson coupled lead islands on Graphene
Suraina Gupta, Santu Prasad Jana, Rukshana Pervin +1
Superconductor-to-metal transition with magnetic field and gate-voltage is studied in a Josephson junction array comprising of randomly distributed lead islands on exfoliated singl…
Enhanced performance of MoS/SiO field-effect transistors by hexamethyldisilazane (HMDS) encapsulation
Santu Prasad Jana, Shivangi, Suraina Gupta +1
Scalable methods for improving the performance and stability of a field-effect transistor (FET) based on two-dimensional materials are crucial for its real applications. A scalable…
A thermal model with AC Josephson effect for a shunted superconducting weak-link
Sourav Biswas, Anjan Kumar Gupta
Superconducting weak-link (WL), behaving like a Josephson junction (JJ), is fundamental to many superconducting devices such as nanoSQUIDs, single-photon detectors, and bolometers.…
Reversibility of Superconducting Nb Weak Links Driven by the Proximity Effect in a Quantum Interference Device
Nikhil Kumar, T. Fournier, H. Courtois +2
We demonstrate the role of proximity effect in the thermal hysteresis of superconducting constrictions. From the analysis of successive thermal instabilities in the transport chara…
Evidence for topological surface states in metallic single crystals of Bi2Te3
Sourabh Barua, K. P. Rajeev, Anjan K. Gupta
Bi2Te3 is a member of a new class of materials known as topological insulators which are supposed to be insulating in the bulk and conducting on the surface. However experimental v…
