Self-powered perovskite CH3NH3PbBr3 field effect transistor with fast response and high sensitivity in sensing

Organic-inorganic hybrid perovskite materials possess advantages over other candidate classes for chemo-sensory materials because of their structural tunability and stability. In this work, we prepared highly qualitied MAPbBr3 perovskite crystals to provide a high carrier mobility to enhance the sen...
