P-GaN Tri-Gate MOS Structure for Normally-Off GaN Power Transistors

Elison de Nazareth Matioli, Pirouz Sohi, Jun Ma, Luca Nela, Catherine Erine, Minghua Zhu

In this letter, we present a new concept for normally-off AlGaN/GaN-on-Si MOS-HEMTs based on the combination of p-GaN, tri-gate and MOS structures to achieve high threshold voltage (V-TH) and low on-resistance (R-ON). The p-GaN is used to engineer the band ...

Investigation on Output Capacitance Losses in Superjunction and GaN-on-Si Power Transistors

Elison de Nazareth Matioli, Halil Kerim Yildirim, Armin Jafari, Palliyage Srilak Nirmana Perera

Low ON-resistance of advanced superjunction (SJ) and GaN-on-Si transistors is of great importance in power converters, however, the anomalous loss in their output capacitance (C OSS ) severely limits their performance. In this work, we use an energy-orient ...
