Halide perovskites have been under the focus for photovoltaic applications where their power conversion efficiencies have soared to efficiencies exceeding 25%. They have also garnered tremendous research interest over recent years for the development of next-generation light-emitting diodes (PeLED) in optical displays and light sources. 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 focus on our efforts on utilising the ionic characteristics of halide perovskites to enable memristive devices that can be employed for neuromorphic applications. The influence of the ionic compositions and interfacial layers in the switching behaviour of the devices would be explained. Going beyond two terminal devices, our recent efforts on three terminal devices would also be covered.
