Abstract
Phototransistors Metal–oxide-based phototransistors conventionally have a limit to their detection range and display a persistent photocurrent (PPC) phenomenon, which may hinder their potential applications in devices. In article number 2006091, Hyun Jae Kim and co-workers review the latest approaches for the absorption layer, according to surface treatment, structural engineering, and the absorption materials. In addition, they also discuss emerging applications and a general outlook. A metal–oxide–semiconductor-based phototransistor structure for light detection is depicted.
