AI Summary
A research team has developed a gallium nitride transistor using diamond as a substrate, resulting in significantly improved heat dissipation. This transistor has potential applications in various fields including 5G communication, weather radar, satellite communications, microwave heating, and plasma processing.
A research team has fabricated a gallium nitride (GaN) transistor using diamond, which of all natural materials has the highest thermal conductivity on earth, as a substrate, and they succeeded in increasing heat dissipation by more than two times compared with conventional transistors. The transistor is expected to be useful not only in the fields of 5G communication base stations, weather radar, and satellite communications, but also in microwave heating and plasma processing.
