| Outline of Final Research Achievements |
Aiming at the fabrication of next-generation ultraviolet laser diodes and light-emitting diodes, creation of growth technique for high-quality zinc oxide thin films using catalytically generated high-energy H2O beam was conducted. As a result, zinc oxide thin films with the high electron mobility greater than 200 cm2/Vs were obtained. By the oxynitrogen gas addition during the ZnO film growth, the decrease in the electron concentration and an observation of neutral acceptor bound exiton emissions. The possibility of the fabrication on p-type zinc oxide films by nitrogen doping was confirmed. By the observation of the H2O beam energy in an adiabatic expansion expansion process in the reaction space, the difference in the beam energy dependent on angular aperture of the nozzles was confirmed.
