Vertically Integrated Dual-memtransistor Enabled Reconfigurable Heterosynaptic Sensorimotor Networks and In-memory Neuromorphic Computing
Srilagna Sahoo, Abin Varghese, Aniket Sadashiva +4
Neuromorphic in-memory computing requires area-efficient architecture for seamless and low latency parallel processing of large volumes of data. Here, we report a compact, vertical…
Enhanced gas sensing performance and all-electrical room temperature operation enabled by a WSe2/MoS2 heterojunction
Sushovan Dhara, Himani Jawa, Sayantan Ghosh +2
Gas sensors built using two-dimensional (2D) MoS2 have conventionally relied on a change in field-effect-transistor (FET) channel resistance or a change in Schottky contact/pn homo…
Electrically Tunable Room Temperature Hysteresis Crossover in Underlap MoS FETs
Himani Jawa, Abin Varghese, Saurabh Lodha
Clockwise to anti-clockwise hysteresis crossover in current-voltage transfer characteristics of field effect transistors (FETs) with graphene and MoS channels holds significant…
Near-direct bandgap / type-II pn heterojunction for enhanced ultrafast photodetection and high-performance photovoltaics
Abin Varghese, Dipankar Saha, Kartikey Thakar +5
PN heterojunctions comprising layered van der Waals (vdW) semiconductors have been used to demonstrate current rectifiers, photodetectors, and photovoltaic devices. However, a dire…
