摘要	Shallow acceptor states in Mg-doped CuAlO2 and their effect on structural, electrical, and optical properties are investigated by combining first-principles calculations and experiments. First-principles calculations demonstrate that Mg substituting at the Al site in CuAlO2 plays the role of shallow acceptor and has a low formation energy, suggesting that Mg doping can increase hole concentration and improve the conductivity of CuAlO2. Hall effect measurements indicate that the hole concentration of the Mg-doped CuAlO2 thin film is 2 orders of magnitude higher than that of undoped CuAlO2. The best room temperature conductivity of 8.0 X 10(-2) S/cm is obtained. A band gap widening is observed in the optical absorption spectra of Mg-doped CuAlO2, which is well supported by the results from first-principles electronic structure calculations.
