Single Crystal Rutile TiO2 upon reduction by heating in an atmosphere of hydrogen becomes a semiconductor, and the conductivity increases with the time and temperature of reduction. The reduction process creates oxygen vacancies with which there are associated two loosely bound electrons. These electrons may be raised to the conduction band by thermal excitation. Hence, an oxygen vacancy behaves like an impurity donor site.
