Can Boron Increase The Efficiency Of LEDs?

Using predictive atomistic calculations and high-performance supercomputers at the National Energy Research Scientific Computing Center (NERSC), researchers Logan Williams and Emmanouil Kioupakis at the University of Michigan found that incorporating the element boron into the widely used InGaN material can keep electrons from becoming too crowded in LEDs, making the material more efficient at producing light. Their paper 'BInGaN alloys nearly lattice-matched to GaN for high-power high-efficiency visible LEDs' was published this month in Applied Physics Letters.
