Electrical Characteristics of in situ Mg-doped beta-Ga2O3 Current-Blocking Layer for Vertical Devices

Sudipto Saha, Lingyu Meng, A F M Anhar Uddin Bhuiyan +4

The lack of p-type doping has impeded the development of vertical gallium oxide (Ga2O3) devices. Current blocking layers (CBL) using implanted deep acceptors has been used to demon…

Simulation studies of Single Event Effects in Ga $_{2}$ O $_{3}$ MOSFETs

Animesh Datta, Uttam Singisetti

In this article, we investigate the Single Events Effects (SEE) leading to Single Event Burnout (SEB) in $β$ -Ga $_{2}$ O $_{3}$ MOSFETs. Using Silvaco TCAD, 2D simulations were performed…
