The National Science Foundation Division of Materials Research awarded $320,000 under the Mathematical and Physical Sciences program (CFDA 47.049) to the Massachusetts Institute of Technology for a collaborative research project on combinatorial solution processing of optical phase change materials. The researchers will develop a high-throughput synthesis and characterization paradigm for accelerated discovery and customization of multi-component phase change alloy thin films tailored for applications in reconfigurable optics. Rather than traditional vacuum deposition methods, the team will harness combinatorial printing of phase change material solutions to facilitate scalable production of custom materials, even with complex multilayer structures. The printed thin films will be characterized using integrated micro-heater arrays to systematically evaluate phase transition kinetics and optical properties under operational conditions. This work aims to address bottlenecks in traditional phase change material discovery and measurement, with potential impacts for energy efficient data communications, active metamaterials, photonic memory, displays and analog computing.
