Characterization of carrier states in CuWO4 thin-films at elevated temperatures using conductometric analysis
چکیده انگلیسی

CuWO4 thin-films were deposited by pulsed laser deposition onto an insulating substrate. The temperature dependence of the electronic conductivity of CuWO4 thin-films was determined over 100–500 °C temperature range in a synthetic air atmosphere. Additionally, variations of conductivity at 300 °C and 500 °C have been measured for oxygen partial pressures (0.1 atm

► The study of surface species in CuWO4 thin-films was carried using conductometry.
► The determination of the apparent activation energy of conduction with temperature is outlined.
► Temperature and O2 concentration effects on the oxygen states was established.
► For the ranges of temperature studied, the identified operating oxygen states were O2− and O−.
