A method for controlling the optical properties of a solid-state film over broad wavelength range is highly desirable and could have significant commercial impact. One such application smart glazing technology where near-infrared solar radiation harvested in winter reflected it summer?an impossibility materials with fixed thermal properties. Here, we experimentally demonstrate first spectrally ...

Abstract Chalcogenide phase change materials (PCMs) have been extensively applied in data storage, and they are now being proposed for high resolution displays, holographic reprogrammable photonics, all-optical neural networks. These wide-ranging applications all exploit the radical property contrast between PCMs’ different structural phases, extremely fast switching speed, long-term stability,...

Phase-change memory is a promising nonvolatile technology based on special class of functional materials ? phase-change (PCMs). PCMs can be reversibly switched between amorphous and crystalline states within the timescale nanoseconds. The switchable used to encode information for data storage applications. Considerable progress has been made in understanding properties states, which frequently ...
