ScholarBank@NUS Repository. https://doi.org/10.1016/S0169-4332(02)00425-7 | Abstract: | We report the optical and electrical properties for highly c-axis oriented ZnO films deposited on Si (0 0 1) and quartz substrates by pulsed laser deposition (PLD) under various deposition conditions such as substrate temperature, laser fluence and oxygen ambient pressure. Dependence of structural, optical and electrical measurements on the substrate temperature reveals improvement of crystalline quality of ZnO films with raising substrate temperature. Optical and electrical properties show different behaviors in vacuum and oxygen ambient with increasing laser fluence. Combined with high laser fluence, oxygen ambient plays an important role in removing defects due to excess zinc or oxygen vacancy. © 2002 Elsevier Science B.V.
