Researchers at the University of California at Los Angeles in the US and Hunan University in Changsha, China, have come up with a new way to grow 2D-layered semiconductor heterostructures whose composition can be controlled by modulating the constituent vapour-phase reactants during growth. The structures produced are single crystals and might be used to make a host of electronics devices, ranging from complementary logic circuits, photovoltaics and photodetectors, to light-emitting diodes and laser diodes…..
