High performance IGZO-based phototransistors by BN/BP interface engineering

Daqing Li et al.

Summary: In this study, a huge improvement in photoresponse performances for IGZO phototransistor devices was achieved by introducing boron nitride (BN)/black phosphorus (BP) interface engineering, leading to a significant suppression of photo-generated carrier recombination in the IGZO channel. This approach resulted in enhanced photoresponsivity and external quantum efficiency, demonstrating the potential of 2D materials interface engineering for high performance oxide-semiconductor based optoelectronic devices.

Precise Turn-On Voltage Control of MIOSM Thin-Film Diodes with Amorphous Indium-Gallium-Zinc Oxide

Kyungho Kim et al.

Summary: Controlling carrier injection into trap states in an insulator by varying oxygen vacancies in the oxide semiconductor is crucial for shifting the turn-on voltage of MIOSM TFDs. By manipulating trap states in the insulator, finely tuned turn-on voltages of MIOSM TFDs can be achieved.
