increase in electrical conductivity with film thickness is caused by the oxygen vacancies and ${\rm SnO}_{2-x}({\rm V …}_{\rm \ddot{O}})_{x}\, {\rm e}_{2x}^\prime$ defects which generate carriers in the films. The increase in electrical conductivity … ionized oxygen vacancies are thought to be responsible for the increase in electrical conductivity at higher annealing …
