A multi-institutional team led by the US Department of Energy’s National Renewable Energy Laboratory (NREL) discovered a way to create new alloys that could form the basis of next-generation semiconductors.   Semiconductor alloys already exist-often made from a combination of materials with similar atomic arrangements, but until now researchers believed it was unrealistic to make alloys of certain constituents.   “Maybe in the past scientists looked at two materials and said I can’t mix thos...
