Carrier recombination manipulation for tunable multicolor emission in two-dimensional transition metal dichalcogenide light-emitting devices
We demonstrate a dual-colored light-emitting device using 2D semiconductors by modulating AC carrier injection through independent electrodes with phase delay, enabling balanced emission from WSe<sub>2</sub> and WS<sub>2</sub> monolayers. This innovative approach allows balanced, dynamically controllable, and spectrally stable emissions from WSe<sub>2</sub> and WS<sub>2</sub> monolayers, significantly enhancing emission control and expanding possibilities in advanced multicolor optoelectronic applications, including integrated photonic circuits and high-resolution display technologies.
