The photoconductive characteristics of undoped ZnO single crystals grown by the hydrothermal method were improved by annealing in oxygen gas. The photocurrent in the visible light region decreased with annealing and became about 1/105 and about 1/104

Non-doped Mg x Zn 1 − x O films (Mg x Zn 1 − x O films) and nitrogen-doped Mg x Zn 1 − x O films (Mg x Zn 1 − x O:N films) were grown epitaxially on Zn faces of ZnO single crystal substrates by the plasma-assisted reactive evaporation (PARE)

Nitrogen-doped (N-doped) ZnO single crystals were prepared by the hydrothermal method. Resistivity of the N-doped ZnO single crystal was 107–108 Ωcm, which was about 104-times higher than that of the non-doped ZnO single crystal. Photocurrent of t

The band gap energy (Eg) of high-quality Mgx Zn1-xO films grown on ZnO (0001) substrates by the plasma-assisted reactive evaporation method using a ZnMg alloy could be estimated by the photocurrent (Iph). Measurement of Iph was more useful than photo
