New gallium oxide-based transistor can handle 8,000 volts
It also has much higher bandgaps than other potential silicon replacements such as silicon carbide (SiC) with 3.4 electron volts and gallium nitride with 3.3 electron volts. This time, the researchers decided to base a MOSFET on gallium oxide and found that despite its super small and thin profile thanks to the ultrawide bandgap, their transistor was able to handle extremely high voltages of
