Highly transparent phototransistor based on quantum-dots and ZnO bilayers for optical logic gate operation in visible-light

Highly transparent optical logic circuits operated with visible light signals are fabricated using phototransistors with a heterostructure comprised of an oxide semiconductor (ZnO) with a wide bandgap and quantum dots (CdSe/ZnS QDs) with a small bandgap. ZnO serves as a highly transparent active cha...
