Superinsulating behavior in granular Pb film on gated few-layer MoS $_{2}$

Suraina Gupta, Santu Prasad Jana, Pawan Kumar Gupta +1

We report a super-insulating behavior, in a device having granular Pb film on back-gated few-layer $Mo S_{2}$ , below an onset temperature same as the critical temperature $T_…

Blocking transition of SrTiO $_{3}$ surface dipoles in MoS $_{2}$ /SrTiO $_{3}$ field effect transistors with counterclockwise hysteresis

Santu Prasad Jana, S Sreesanker, Suraina Gupta +1

A counterclockwise hysteresis is observed at room temperature in the transfer characteristics of SrTiO $_{3}$ (STO) gated MoS $_{2}$ field effect transistor (FET) and attributed to bista…

Inhomogeneous hysteresis in local STM tunnel conductance with gate-voltage in single-layer MoS $_{2}$ on SiO $_{2}$

Santu Prasad Jana, Suraina Gupta, Anjan Kumar Gupta

Randomly distributed traps at the MoS $_{2}$ /SiO $_{2}$ interface result in non-ideal transport behavior, including hysteresis in MoS $_{2}$ /SiO $_{2}$ field effect transistors (FETs). Thus tr…
