Experiment Investigation of Photo-Assisted Tunneling in a 2D Magnet-Semiconductor Tunnel Junction

ORAL

Abstract

A magnetic tunnel junction consists of two magnetic layers separated by a thin tunnel barrier and features significant magneto-tunneling resistance that depends on the alignment of spins in the magnetic layers. We introduce a novel device structure made from a monolayer semiconductor and a 2D magnetic metal Fe₃GeTe₂ with a BN tunnel barrier. This device leverages both the magnetization of the 2D magnet and light polarization to control tunneling resistance.
