Dielectric Reliability and Interface Trap Characterization in MOCVD grown In-situ Al $_{2}$ O $_{3}$ on $β$ -Ga $_{2}$ O $_{3}$

Saurav Roy, Arkka Bhattacharyya, Carl Peterson +1

In this article, we investigate the in-situ growth of Al $_{2}$ O $_{3}$ on $β$ -Ga $_{2}$ O $_{3}$ using metal-organic chemical vapor deposition (MOCVD) at a high temperature of 800°C. The Al$_2…
