Visible and Infrared Nanocrystal-based Light Modulator with CMOS Compatible Bias Operation

International audience; Nanocrystals are now established light sources, and as synthesis and device integration have gained maturity, new functionalities can now be considered. So far, the emitted light from a nanocrystal population remains mostly driven by the structural properties (composition, size, shape) of the particle, and only limited post-synthesis tunability has been demonstrated. Here, we explore the design of light amplitude modulators using a nanocrystal-based light-emitting diode operated under reverse bias. We demonstrate strong photoluminescence modulations for devices operating in the visible and near telecom wavelengths using low bias operations (
