Abstract(in English) | We have obtained n-type conductive Si-doped AlN and Al_xGa_1-xN with high Al content by intentionally controlling the Si dopant density, [Si]. The Si-doped AlN showed the n-type conduction when the [Si] was less than 3x10^19 cm^-3. When the [Si] was more than 3x10^19 cm^-3, it became highly resistive due to the self-compensation of Si donors. This indicates that the self-compensation plays an important role at higher [Si] and determines the upper doping limit of Si for AlGaN. For x > 0 49 the ionization energy of Si donor increased sharply with increasing Al content. This resulted in a sharp decrease in the highest obtainable electron concentration with increasing Al content for the Si-doped Al_xGa_1-xN. |
