Abstract

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 and WS monolayers. This innovative approach allows balanced, dynamically controllable, and spectrally stable emissions from WSe and WS monolayers, significantly enhancing emission control and expanding possibilities in advanced multicolor optoelectronic applications, including integrated photonic circuits and high-resolution display technologies.

摘要

我们展示了一种使用二维半导体的双色发光器件，通过具有相位延迟的独立电极调制交流载流子注入，实现了WSe和WS单分子层的平衡发光。这种创新方法允许WSe和WS单分子层实现平衡、动态可控且光谱稳定的发光，显著增强了发光控制能力，并拓展了包括集成光子电路和高分辨率显示技术在内的先进多色光电子应用的可能性。
