Electrical conductivity measurements in an undoped titanium dioxide thin film have been carried out as a function of temperature (180- 320 K). The film has been deposited onto glass substrates by a d.c. magnetron-sputtering method, using water vapors as reactive gas. Analysis of the data showed that temperature dependence on the electrical conductivity was well described by the Mott type variable range hopping (VRH) law, suggesting that the density of states at the Fermi level is constant in this temperature range.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
