Zinc selenide (ZnSe) thin films (d = 0.10 – 1.20 μm ) were deposited onto glass substrates by the quasi-closed volume technique under vacuum. The film structure was studied by X-ray diffraction technique, transmission electron microscopy and atomic force microscopy. The investigations shown thin films are polycrystalline and have a cubic structure. It was experimentally found that the films with stable structure and reproducible properties can be obtained if they were subjected to a heat treatment. The spectral dependences of transmission and absorption were studied. Optical energy gap, calculated from the absorption spectra for the studied samples was in the range Eg = 2.42 – 2.72eV. These values are in a good agreement with the values of Eg obtained for bulk ZnSe crystals..

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.
