Low-Temperature Pulse Irradiation Technique Enables Flexible Optoelectronic Devices

Description

The synthesis of metallic inorganic compound thin films typically requires high-temperature processes, which hampers their applications on flexible substrates. Recently, a research team at City University of Hong Kong (CityUHK) developed a pulse irradiation technique that synthesizes a variety of thin films in an extremely short time under ultra-low temperature. The strategy effectively addresses the compatibility and cost issues of traditional high-temperature synthesis, and the prepared thermoelectric films exhibit excellent optoelectronic performance in the visible and near-infrared spectrum range, which is promising for wearable electronics and integrated optoelectronic circuits.
