Abstract

Transformation of unipolar n‐type semiconductor behavior to ambipolar and finally to unipolar p‐type behavior in CH3NH3PbI3 microplate field‐effect transistors by thermal annealing is reported. The photoluminescence spectra essentially maintain the same features before and after the thermal annealing process, demonstrating that the charge transport measurement provides a sensitive way to probe low‐concentration defects in perovskite materials.
