摘要
采用金属有机化学气相沉积(MOCVD)方法,由NO和N2O混合气体在玻璃衬底上沉积了p型ZnO薄膜.NO和N2O流量分别为40和25 sccm时,得到最低电阻率5.52Ω·cm, 同时样品的空穴浓度最高,为2.17×1018cm-3,电性能的稳定性也最好.全部样品放置四个月后仍为p型,但电阻率增大.
Nitrogen-doped p-type zinc oxide (ZnO) thin films were deposited on glass substrates by metalorganic chemical vapor deposition (MOCVD). The p-type ZnO, with the lowest resistivity of 5.52 Omega(.)cm and the highest hole concentration of 2.17 x 10(18)CM(-3), can be achieved at the NO and N2O flow rates of 40 and 25sccm, respectively, and the sample was most stable. Four months later, all samples still showed p-type conduction, but the resistivities were increased.
