Abstract

In this paper, our interest is focused on a theoretical investigation of chains based on Cd1-xZnS quantum dots inserted in an insulating material. This system, supposed as a succession of flattened cylindrical quantum dots with a finite barrier height at the boundary, is treated with use a novel potential model. The super lattice band structure, the electron effective mass of the fundamental mini band and the coupling have been studied versus the inter-quantum dot separation for different zinc contents. The obtained results showed that the CdS system is the most adapted to have a super lattice behavior. Moreover, this study is of a great interest and can be considered as a helpful support for designing a new class of devices.
