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

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

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 ...

p-GaN field plate for low leakage current in lateral GaN Schottky barrier diodes

Elison de Nazareth Matioli, Luca Nela, Catherine Erine

High-voltage gallium nitride Schottky barrier diodes (SBDs) suffer from large off-state leakage current, which further degrades during operation at high temperatures and limits the device blocking capabilities. The key to achieving low off-state leakage is ...

p-NiO Junction Termination Extensions for High Voltage Vertical GaN Devices

Elison de Nazareth Matioli, Remco Franciscus Peter van Erp, Luca Nela, Riyaz Mohammed Abdul Khadar, Catherine Erine, Taifang Wang, Alessandro Floriduz, Pirouz Sohi, Reza Soleiman Zadeh Ardebili

In this paper, we illustrate the use of RF-sputtered p-NiO to fabricate Junction Termination Extensions (JTEs) for high-performance vertical GaN-on-Si Schottky Barrier Diodes (SBDs). The GaN epitaxial structures were grown on 6-inch Si wafers by MOCVD. The ...

Figures-of-Merit of Lateral GaN Power Devices: modeling and comparison of HEMTs and PSJs

Elison de Nazareth Matioli, Luca Nela, Catherine Erine, Maria Vittoria Oropallo

In this work, we propose a simple and yet accurate physical model to describe the figures-of-merit (FOMs) of lateral GaN power devices. While the performance limit of vertical devices is well understood, the FOMs of lateral devices are not properly describ ...
