Abstract(in English) | A combination of a wet chemical process in NH_4OH solution and a ECR-N_2 plasma treatment was found to be effective in reducing the surface band bending on GaN surfaces. A nitrogen-vacancy-related surface state was introduced near Ec-0.5 eV on the GaN surfaces exposed to H_2 plasma. A SiN_x/GaN structure prepared by ECR-CVD process showed good interface properties with low interface state densities. An ultrathin (below 4nm) AlO_X layer was successfully fabricated on the AlGaN surface and applied to insulated-gate type GaN/AlGaN heterostructure filed-effect transistors (IG-HEET). |
