Halide perovskites have been under the focus for photovoltaic applications where their power conversion efficiencies have soared to efficiencies exceeding 26%. They have also garnered tremendous research interest over recent years for the development of next-generation light-emitting diodes and detectors. The spotlight on this class of semiconducting material stems from several of its enviable traits such as long carrier diffusion length, defect tolerance, high colour purity, and spectral bandgap tunability which spans across the visible and infrared spectrum. This talk will cover our recent efforts in utilising the ionic characteristics of halide perovskites to enable memristive devices that can be employed for neuromorphic applications. The talk will cover 2 and 3 terminal memristive devices as well as our efforts to utilise colour changing LEDs and photovoltaic devices as unconventional computing elements.
