Abstract: ZnO thin films were prepared on the smooth nucleation surfaces of freestanding CVD thick diamond films by metal organic chemical vapor deposition (MOCVD) with two-step growth method. The growth and electrical properties of the ZnO films are characterized experimentally. The ZnO film deposited at a substrate temperature of 600 ℃ exhibited a clean surface with c-preferred orientation and had a mobility of 3.79 cm2/(V·s).
