Outline of Final Research Achievements |
In order to prepare ZnO films on non-heat-resistant and low-cost plastic substrates, growth temperature should be reduced less than 100 degrees Celsius. From such a viewpoint, we have recently demonstrated highly transparent and conductive ZnO films grown by atomic-oxygen-assisted molecular beam epitaxy growth. In this study, the ZnO films prepared under various growth conditions were carefully characterized by X-ray diffraction, I-V measurements and optical transmittance measurements to investigate the structural, electrical and optical properties of the ZnO films on polyethylene naphthalate (PEN), polyethylene terephthalate (PET) and polycarbonate (PC) substrates.
