چکیده
This work reported the design and the development of a physical simulation model of AlGaN/GaN High Electron Mobility Transistor (HEMTs). Our main aim was to ascertain the influence of technological parameters (the gate length, the AlGaN layer thickness, and doping concentration (Nd)) on the drain-source current Ids [Vds, Vgs], the Ids-Vgs characteristics and the transconductance gm by using a commercial software Comsol Multiphysics version. 5.1. On the other hand, this work was strengthened by the experimental data that confirmed the validity of the present model.

Effect of electron-beam irradiation on leakage current of AlGaN/GaN HEMTs on sapphire
This study examined the effect of electronbeam (E-beam) irradiation on the electrical properties of n-GaN, AlGaN and AlGN/GaN structures on sapphire substrates. E-beam irradiation resulted in a significant decrease in the gate leakage current of the n-GaN, AlGaN and HEMT structure from 4.0×10 -4 A, 6.5×10 -5 A, 2.7×10 -8 A to 7.7×10 -5 A, 7.7×10 -6 A, 4.7×10 -9 A, respectively, at a drain volta...

متن کاملAnalysis of Passivation-Film-Induced Stress Effects on Electrical Properties in AlGaN/GaN HEMTs
Effects of stress in passivation films on the electrical properties of (0001) AlGaN/GaN HEMTs are numerically analysed in the framework of the edge force model with anisotropical characteristics in elastic properties of group-III nitrides explicitly considered. Practical compressive stresses in passivation films induce negative piezoelectric charges below the gates and bring forth a-few-volt sh...

A new non-linear method for design and analysis of solid state power amplifiers is presented and applied to an aluminum gallium nitride, gallium nitride (AlGaN-GaN) high electron-mobility transistor (HEMTs) on silicon-carbide (SiC) substrate for Ku band (12.4 13.6 GHz) applications. With combining output power of 8 transistors, maximum output power of 46.3 dBm (42.6 W), PAE of 43% and linear ga...
متن کاملDegradation of AlGaN/GaN HEMTs below the “critical voltage”: a time-dependent analysis
This paper describes an extensive study of the reversebias degradation of AlGaN/GaN-based High Electron Mobility Transistors. The analysis was carried out by means of combined electrical characterization and timeresolved electroluminescence measurements. Results indicate that: (i) AlGaN/GaN HEMTs can degrade even below the “critical voltage” identified by means of stepstress experiments. (ii) d...
