Theoretical simulations reveal that layered semiconductors
with magnetic interfaces are potent catalysts for solar energy capture and
conversion
Semiconductor nanostructures are poised to play a big role
in future solar-powered hydrogen generation systems, according to a new study
by researchers at the A*STAR Institute of High Performance Computing1. Hui Pan
and Yong-Wei Zhang report that model interfaces made from gallium nitride (GaN)
and zinc oxide (ZnO) semiconductors have tunable magnetic and light-harvesting
capabilities — factors that can greatly improve the photocatalytic
transformation of water into hydrogen fuel.
