Research Abstract |
We studied on the optical and electrical properties of oxide semiconductors and their applications to solar-blind UV detectors. The photoconductor device made of sol-gel synthesized gallium oxide film operated as a solar blind device showing its sensitivity in a wavelength range of 245-260nm. We also studied .Zr1-_xTi_xO_2as a material whose optical band-gap can be controlled by the molar fraction of Zr and Ti. We showed .Zr1-_xTi_xO_2is promising as solar-blind materials showing that their band-gap can be controlled in the range of 3.6-5.2eV, including the solar-blind range.
