Gate reliability enhancement of p-GaN gate HEMTs with oxygen compensation technique

open access: yesApplied Physics Express
Abstract Improved p-GaN gate reliability is achieved through a simple oxygen compensation technique (OCT), which involves oxygen plasma treatment after gate opening and subsequential wet etching. The OCT compensates for the Mg acceptors near the p-GaN surface, leading to an extended depletion region under the same gate bias and thus ...

Room Temperature Rejuvenation Technology for Irradiated Gallium Nitride Transistors

open access: yesAdvanced Materials Technologies, Volume 10, Issue 24, December 17, 2025.
High temperature annealing has been the main defect mitigation technology since the Bronze age. We propose a room temperatureannealing technique that could be effective for electrically conducting materials. The new technique is demonstrated on a Gallium Nitride high electron mobility transistor undergoing radiation damage.

Demonstration of GaN‐Based HEMTs Using Extremely Thin h‐BN Passivation Layer and Air Spacer for the RF Performance Improvement

open access: yesAdvanced Electronic Materials, Volume 11, Issue 20, December 3, 2025.
An extremely thin h‐BN passivation layer and an air spacer are employed in the fabrication of GaN‐based HEMTs. While the DC characteristics of the h‐BN‐passivated GaN‐based HEMTs are identical to those of conventional SiN‐passivated devices, the RF performance is improved due to the formation of the air spacer and the reduction of parasitic ...

E-Mode p-n Junction/AlGaN/GaN (PNJ) HEMTs [PDF]

open access: yes, 2020
In this work, we demonstrate a GaN-based p-n junction gate (PNJ) HEMT featuring an n-GaN/ p-GaN/AlGaN/GaN gate stack. Compared to the more conventional p-GaN gate HEMT with a Schottky junction between the gate metal and p-GaN layer, the p-n junction can ...

High-Performance Ultraviolet Photodetector Arrays Based on Recessed-Gate HEMT with a Buried p‑GaN Layer [PDF]

open access: yes
GaN, due to its large band gap and high carrier mobility, has been widely used in fast-response ultraviolet (UV) photodetectors (PDs). The existing junction-based and two-dimensional electron gas (2DEG)-based devices have different focuses on the ...
