Edge emission from 265~nm UV-C LEDs grown by MBE on bulk AlN
Shivali Agrawal, Hsin-Wei S. Huang, Debaditya Bhattacharya +6
UV-C LEDs pseudomorphically grown by MBE on bulk AlN substrates emitting at 265 nm are demonstrated. High current density up to 800 A/cm, 5 orders of on/off ratio, and low diff…

Kramers' escape problem for white noise driven switching in ferroelectrics
Madhav Ramesh, Amit Verma, Arvind Ajoy
A simulation-based study of stochastic resonance (SR) in a ferroelectric capacitor is presented. The SR phenomenon involves the detection of weak signals by adding an optimal amoun…

Lorentzian Switching Dynamics in HZO-based FeMEMS Synapses for Neuromorphic Weight Storage
Shubham Jadhav, Kaustav Roy, Luis Amaro +6
Neuromorphic computing demands synaptic elements that can store and update weights with high precision while being read non-destructively. Conventional ferroelectric synapses store…
