Abstract(in English) | In this study, we attempted the p/n conductivity control of epitaxial AlInN films grown by metalorganic chemical vapor deposition (MOCVD) by means of the impurity-doping of Si and Mg atoms and the polarization-doping. First, The Si-doped AlInN films with a Si concentration of approximately 8 × 10^18 cm^-3 with a thickness of 300 nm were grown nearly lattice-matched to c-plane GaN-on-sapphire templates. By using TLM method, the vertical direction resistivity of the 300-nm-thick n-type AlInN film was estimated to be 5.8×10^-4 Ωcm^2. Then, Mg doped AlInN films with a thickness of approximately 100 nm were grown on c-plane GaN-on-sapphire templates, the AlInN film showed a relative smooth surface at a high Mg concentration of approximately 1.5 × 10^19 cm^-3. Finally, graded AlInN films with a thickness of 100 nm were grown on c-plane GaN-on-sapphire templates, aiming at the generation of polarization-induced holes. It was confirmed that an AlInN film was grown with an InN molar fraction variation ranging from 0.14 to 0.19. The Hall effect measurement showed less temperature dependence of holes, which confirmed the generation of polarization-induced holes. |
