文摘
- •
The in-situ measurement the conductance during irradiation reveals the percolation of the defects.
- •
Oxygen vacancies are the main defects by XPS.
- •
The resistance is correlated with the oxygen vacancy concentration.
- •
The temperature dependence of the resistance shows an insulator-metal transition.
