Abstract(in English) | Lightly-Mg-doped p-type gallium nitride (GaN) with the Mg concentration of $6.5times 10^{16}~mbox{cm}^{-3}$ was characterized by Hall-effect measurements for analysis of the hole concentration and mobility. The Mg-doped p-GaN with the thickness of $1~mumbox{m}$ was grown on free-standing GaN substrate by metal-organic vapor-phase epitaxy, the threading dislocation density of which was $4times 10^{6}~mbox{cm}^{-2}$ measured by cathodoluminescence mapping. Hall-effect measurements of the p-GaN were carried out at a temperature in the range from 160 to 450K. It was revealed a low compensation ratio of less than 1% and the hole mobility of $33~mbox{cm}^2mbox{/Vs}$ at room temperature. |
