| Research Abstract |
To develop a novel ultra-violet (UV) light-emitting device using UV emission from Gd in AlN films, film fabrication and film properties were studied. By a low-cost fabrication method of radio-frequency (RF) sputtering on Si wafers, relations between fabrication conditions and film properties were examined, and those conditions to obtain UV emission of around 315nm at room temperature were found. Optical measurements to find emission mechanism and film fabrication by molecular-beam growth (MBE) were also carried out.
