Control of positive and negative photo- and thermal-responses in a single PbI2@CH3NH3PbI3 micro/nanowire-based device for real-time sensing, nonvolatile memory, and logic operation

Abstract

By introducing PbI2 quantum dots as trap centres in CH3NH3PbI3 micro/nanowires, abnormal optical and electrical responses can be achieved, allowing versatile integration of sensing, memory, and operation for optical and thermal data.
