Photo memtransistor based on CMOS flash memory technology on Graphene with neuromorphic applications
arXiv:2005.06861 · doi:10.1021/acsphotonics.1c00664
Abstract
Graphene holds a great promise for a number of diverse future applications, in particular related to its easily tunable doping and Fermi level by electrostatic gating. However, as of today, most implementations rely on electrical doping via the application of continuous large voltages to maintain the desired doping. We show here how graphene can be implemented with conventional semiconductor flash memory technology in order to make programmable doping possible, simply by the application of short gate pulses. We also demonstrate how this approach can be used for a memory device, and also show potential neuromorphic capabilities of the device. Finally, we show that the overall performance can be significantly enhanced by illuminating the device with UV radiation. Our approach may pave the way for integrating graphene in CMOS technology memory applications, and our device design could also be suitable for large scale neuromorphic computing structures.
