Abstract
We successfully fabricate a P-doped ZnO thin film on the GaAs substrate at O2 ambient. And then we apply the post annealing process in 800℃ with in 3 minutes.The resistivity of the film is 0.00096Ω-cm and the hole concentration is 2.244×1020 cm-3. The p-type film exits the acceptor-like complexes of AsZn-2VZn. The structure of the ZnO film has been changed due to the As doped. It helps P-doped to increase the PZn-2VZn complexes. The P-dopant and the Ga-dopant in the ZnO film form the acceptor-donor-acceptor complexes and the hole concentration will be inceased and promote the property of p-type ZnO film.
