Organolead halide perovskites are used for low-operating-voltage multilevel resistive switching. Ag/CH3 NH3 PbI3 /Pt cells exhibit electroforming-free resistive switching at an electric field of 3.25 × 10(3) V cm(-1) for four distinguishable ON-state resistance levels. The migration of iodine interstitials and vacancies with low activation energies is responsible for the low-electric-field resistive switching via filament formation and annihilation.
有机卤化铅钙钛矿用于低工作电压多电平电阻开关。Ag/CH3 NH3 PbI3 /Pt 电池在 3.25×10(3)V/cm(-1)的电场下表现出无需电成型的电阻开关，具有四个可区分的导通状态电阻电平。低活化能碘填隙原子和空位的迁移通过丝的形成和消失导致了低电场电阻开关。
