Compositionally graded contact layers for MOCVD grown high Al-content AlGaN transistors
Towhidur Razzak, Seongmo Hwang, Antwon Coleman +7
In this letter, we design and demonstrate an improved MOCVD grown reverse Al-composition graded contact layer to achieve low resistance contact to MOCVD grown ultra-wide bandgap (U…
