Anatomy of nanomagnetic switching at a 3D Topological Insulator PN junction
Hamed Vakili, Yunkun Xie, Samiran Ganguly +1
A P-N junction engineered within a Dirac cone system acts as a gate tunable angular filter based on Klein tunneling. For a 3D topological insulator with substantial bandgap, such a…
A Physics Based Multiscale Compact Model of p-i-n Avalanche Photodiodes
Sheikh Z. Ahmed, Samiran Ganguly, Yuan Yuan +4
III-V material based digital alloy Avalanche Photodiodes (APDs) have recently been found to exhibit low noise similar to Silicon APDs. The III-V materials can be chosen to operate…
Computing and Memory Technologies based on Magnetic Skyrmions
Hamed Vakili, Wei Zhou, Chung T Ma +13
Solitonic magnetic excitations such as domain walls and, specifically, skyrmionics enable the possibility of compact, high density, ultrafast,all-electronic, low-energy devices, wh…
