衬底位置对化学气相沉积法制备的磷掺杂p型ZnO纳米材料形貌和特性的影响
Influences of the substrate p osition on the morphology and characterization of phosphorus dop ed ZnO nanomaterial
摘要
Abstract
One-dimensional phosphorus doped ZnO nanowires and nanonails are prepared on Si substrate without employing any metal catalyst by chemical vapor deposition method. Field-emission scanning electron microscopy shows that the samples located downstream 1.5 cm away from the source material are of nanowire structure and located 1 cm above source materials of nanonail structure, and the growth mechanisms of phosphorus doped ZnO nanostructures with different morphologies are discussed. The photoluminescence properties of phosphorus doped ZnO nanowires and nanonails are studied at a temperature of 10 K. The phosphorus related acceptor emissions are observed. Furthermore, the current-voltage (I-V ) measurement based on the ZnO nanostructures/Si heterojunctions shows a typical semiconductor rectification characteristic with positive open electric fields being 4.8 and 3.2 V, respectively.关键词
