Fabrication and Enhanced Rectifying Performance of Zn1-xCoxO Nanowall Vertically Growing on Si Wafer
Mesocrystalline ZnO and Co-doped ZnO nanowall/p-Si heterojunctions are prepared by a chemical precursor route, which exhibits a rectifying behavior with a lower turn-on voltage tuned by Co2+ dopant concentration.
