  The advent of memristors and resistive switching has transformed solid state
physics, enabling advanced applications such as neuromorphic computing.
Inspired by these developments, we introduce the concept of Mem-emitters,
devices that manipulate light emission properties of semiconductors to achieve
memory functionalities. Mem-emitters, influenced by past exposure to stimuli,
offer a new approach to optoelectronic computing with potential for enhanced
speed, efficiency, and integration. This study explores the unique properties
of transition metal dichalcogenides-based heterostructures as a promising
platform for Mem-emitter functionalities due to their atomic-scale thickness,
tunable electronic properties, and strong light-matter interaction. By
distinguishing between population-driven and transition rate-driven
Mem-emitters, we highlight their potential for various applications, including
optoelectronic switches, variable light sources, and advanced communication
systems. Understanding these mechanisms paves the way for innovative
technologies in memory and computation, offering insights into the intrinsic
dynamics of complex systems.
