Hole conductivity and acceptor density of p-type CuGaO2 nanoparticles determined by impedance spectroscopy: The effect of Mg doping

- The main electronic properties of p-type CuGaO2 delafossite have been determined by impedance spectroscopy.
- Hole conductivity of 1-10 μS cm−2 has been measured for undoped and Mg doped CuGaO2.
- The capacitive response of the CuGaO2 depends on the synthetic history of the material.
