Stanford breakthrough could make better chips cheaper

Researchers at Stanford University have come up with a new way to make chips and solar panels using gallium arsenide, a semiconductor that beats silicon in several important areas but is typically too expensive for widespread use. For several decades, silicon has been the go-to semiconductor for electronics. It's abundant and cheap, and manufacturing processes are well understood, but it's not always the best choice. Electrons move faster through gallium arsenide than through silicon, which make...
