Room-temperature electrical control of polarization and emission angle in a cavity-integrated 2D pulsed LED

Abstract

2D semiconductors offer a promising platform for the realization of compact and CMOS-compatible optoelectronic components. Here, the authors report the realization of light-emitting diodes based on 2D WSe2 integrated with a planar cavity, showing the electrical control of the emission angle and polarization at room temperature.
