People love their electric cars. But not so much the bulky batteries and related power systems that take up precious cargo space. Help could be on the way from a gallium oxide-based transistor under development at the University at Buffalo.

In a study published in the June edition of IEEE Electron Device Letters, electrical engineers describe how the tiny electronic switch can handle more than 8,000 volts, an impressive feat considering it’s about as thin as a sheet of paper.

The tr...
