Aluminum-doped ZnO (AZO) films are deposited onto the glass substrate by RF magnetron sputtering method. The influence of oxygen concentration in flow sputtering gas on structure and optical properties of AZO are studied. The X-ray diffraction (XRD) shows that the films are highly oriented with their crystallographic c-axis perpendicular to the substrate and that the grain size is influenced by oxygen concentration. The AZO films have high optical transmission in the visible range. The decrease of bandgap energy Eg with increasing oxygen concentration in the flow sputtering gas is described by the Burstein-Moss effect..

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.
