The heterojunction of SiO2/ ZnSe /SiO2 was prepared by electron beam evaporation. SiO2 was used as electron acceleration layer and ZnSe was taken as the luminescent material. Luminescence due to direct bombardment by accelerated electrons in a semiconductor thin film adjacent to the phosphor material layer was observed, which was called cathodoluminescence-like (CL-like) because are electrons accelerated in solid but not in vacuum. This new phenomenon can provide a new way to realize blue electroluminescence. The threshold voltage of the device is 40V. The dependence of CL-like intensity on applied voltage and frequency were studied in detail.

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.
