"remote epitaxy: high-quality crystal film grown on substrate, guided by its atomic structure through thin buffer layer, peeled off... grew crystals through carbon buffer layers up to 7 nm thick (previous limit <1 nm) while maintaining alignment with substrate... substrate dislocations enable long-distance electrostatic interactions guiding crystal film growth/ structure... widens material choices/ improves processing window... scalable membrane release, enables wafer-recycling... built photodetector as proof-of-concept"
