Open AccessA quantitative approach for trap analysis between Al0.25Ga0.75N and GaN in high electron mobility transistors
The characteristics of traps between the Al0.25Ga0.75N barrier and the GaN channel layer in a high-electron-mobility-transistors (HEMTs) were investigated. The interface traps at the Al0.25Ga0.75N/GaN interface a...
