ZnO thin flms prepared by anodic oxidation from metal Zn are investigated.It is shown that the as-prepared anodic ZnO flm has a high resistivity of~105 Ωm.
In the exhausting process of screw vacuum pump,there is internal air leakages from the high pressure discharge side to the low pressure suction side,which a
It was broadly recognized that H2 partial pressure(PH2)in the carrier gas plays a crucial role in graphene CVD growth.Here we present our recent studies on
