The electronic structures of CdTe/ZnTe core/shell structure quantum dots (QDs) has been investigated using the single-band effective mass approximationand first-order perturbation approximation theory. The electronic structure of CdTe/ZnTe QDs is a typical type-II band structure, andthe electron and hole carries would be localized in the core and shell regions respectively. The overlap integral of wave function of them and bandgap energy vary with the changing of core radius and/or shell thickness due to quantum confinement effect. The electronic and optical properties could be tuned by varying the size of QDs..

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.
