Abstract:The
facile ionic transport in all-inorganic CsPbX3 is
crucial for the switching behavior and reliability of ion migration-based
memristors. This work presents a method of halide ion doping to reduce
the bromine vacancies on the surface of CsPbBr3 quantum
dots (QDs) and enhance the migration barriers of bromine ions. This
improves the performance of memristors and achieves a more stable
resistive switching process. The switching voltages (V
SET/V
RESET) for the CsPb(Br0.93I0.07)3 QD-based device are 0.92
V/–3… Show more
