WebIn this work, the dual junction-high-electron-mobility-transistor (DJ-HEMT) was investigated. The thin AlGaN was grown between the p-GaN gate and gate metal. In the TCAD simulations, the band gap and electric field were shown in this letter, proving the dual junction forming. Moreover, DJ-HEMT shows the high gate voltage swing due to the dual … Web1 de jun. de 2024 · The conventional p-GaN gate HEMT is fabricated by etching technology or selective epitaxial growth technology . Recently, a special approach by using hydrogen plasma treatment to realise the p-GaN gate HEMT has been proposed and high-performance small device has been demonstrated . In this Letter, we reported a 49.7 mm …
WebCommercially available normally-off GaN power high-electron-mobility transistor (HEMT) devices have typically adopted a p-GaN gate structure. In the gate region, there exist a Schottky junction (between gate electrode and the p-GaN layer) and a p-GaN/AlGaN/GaN heterojunction. As the p-GaN layer is not directly shorted to the gate electrode and … WebAbstract: In this letter, 600-V normally-OFF ${\rm SiN}_{x}$ /AlGaN/GaN metal–insulator–semiconductor high-electron-mobility transistor (MIS-HEMT) is reported. …
