New faculty member leads research on semiconductor alloys

A multi-institutional team led by the U.S. Department of Energy's National Renewable Energy Laboratory discovered a way to create new alloys that could form the basis of next-generation semiconductors.
The team includes corresponding author Aaron Holder, who recently joined the CU Boulder Department of Chemical and Biological Engineering. Holder is a co-PI of the NREL-led Energy Frontiers Research Center, the , and will hold a joint appointment between NREL and CU.
Semiconductor alloys already existÌý — 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 those two. What we're saying is think again," Holder said. Holder isÌýcorresponding author of a . "There is a way to do it."
