Rational design of Al2O3/2D perovskite heterostructure dielectric for high performance MoS2 phototransistors

Abstract

Designing high-performance photodetectors based on hybrid perovskites remains a challenge. Here, the authors demonstrate that Al2O3/2D perovskite heterostructure can be utilized as photoactive dielectric for high-performance MoS2 phototransistors with broadband photoresponse, high photogain and reliability operation.
