摘要：
Li-doped ZnO nanorods was grown on n-Si (111) substrate by chemical vapor deposition. XRD pattern showed that the nanorods are pure wurtzite ZnO of hexagonal crystal structure without any other oxide, such as Li2O. Hall effect experiment under Van der Pauw configuration showed that Li-doped ZnO nanorods behave the p-type conductivity with hole concentration of 6.72×1016 cm-3 and a Hall mobility of 2.46 cm2 ·V-1·s-1. A neutral acceptor-bound exciton emission (A°X) was confirmed by the measurements of temperature-dependent photoluminescence (PL) spectra. The optical acceptor energy level is calculated to be about 142 meV.
