Perovskite-GST hybrid platform for optical memristors with complex optical response

This study explores the optical properties of a perovskite-GST hybrid platform, revealing a remarkable, up to twofold, increasing of photoluminescence intensity of halide perovskite
thin film by switching the phase of GST substrate from amorphous to crystalline. The underlying mechanisms responsible for this strong modulation in photoluminescence intensity
are related to interaction between the halide perovskite and the GST substrate, which we are investigating through comprehensive morphological and optical characterization techniques, highlighting the different reflectance properties of the crystalline and amorphous phases of GST. We consider this hybrid platform as a promising architecture for a neuromorphic system, leveraging the volatile properties of halide perovskites with the non-volatile characteristics of GST. This architecture aims to mimic the functionalities of the human brain, including the behavior of neurons and synapses, thus opening new avenues for the development of energy-efficient and highly adaptive computing systems. Our findings contribute to a deeper understanding of hybrid perovskite-GST platform and its potential in future technological applications in neuromorphic systems.
