Achieving UV to Infrared AC electroluminescence in MOS capacitors (Invited Paper)

18 August 2024 • 10:50 AM - 11:20 AM PDT

Abstract

In this talk, I will introduce an electroluminescent (EL) device that overcomes the Schottky barrier for efficient UV to IR emission based on a metal-oxide-semiconductor (MOS) capacitor structure. It combines a MOS capacitor with a carbon nanotube network and transition-metal dichalcogenide monolayers. By applying AC voltage, it emits across a wide range of bandgaps, bypassing the need for energy level alignment. This device shows minimal dependence on Schottky barrier height, achieving bright EL in materials with varied thicknesses or mobilities. This AC EL via MOS capacitor device offers a new avenue for UV light sources and optoelectronic applications.
