摘要：

Methylammonium lead bromide (CH3NH3PbBr3 or MAPB) perovskite semiconductors are a potential low-cost option for high energy resolution semiconductor detectors for gamma and neutron sensing. MAPB has recently been demonstrated for its ability to sense alpha particles and neutrons, and pertinent electronic properties have previously been reported. In this presentation, we report on several techniques of improving detector performance to achieve better spectroscopic performance for gamma sensing. These methods include anion and partial cation substitutions of MAPB to improve carrier transport and limit ionic conductivity and several surface treatment and metallization techniques for improved carrier extraction and minimization of device polarization.
