The Emergence\nof Mem-Emitters

The advent of memristors and resistive switching has\ntransformed\nsolid-state physics, enabling advanced applications such as neuromorphic\ncomputing. Inspired by these developments, we introduce the concept\nof Mem-emitters, devices that manipulate light-emission properties\nof semiconductors to achieve memory functionalities. Mem-emitters,\ninfluenced by past exposure to stimuli, offer a new approach to optoelectronic\ncomputing with potential for enhanced speed, efficiency, and integration.\nThis study explores the unique properties of transition-metal dichalcogenide-based\nheterostructures as a promising platform for Mem-emitter functionalities\nbecause of their atomic-scale thickness, tunable electronic properties,\nand strong light–matter interaction. When distinguishing between\npopulation-driven and transition rate-driven Mem-emitters, we highlight\ntheir potential for various applications, including optoelectronic\nswitches, variable light sources, and advanced communication systems.\nUnderstanding these mechanisms paves the way for innovative technologies\nin memory and computation, providing insights into the intrinsic dynamics\nof complex systems.
