The present work is aimed to investigate theoretically the electronic properties of superlattices based on Cd 1-x Zn x S quantum dots embedded in an insulating material. This system, considered as a series of flattened cylindrical quantum dots with a finite barrier at the boundary, is studied using the tight binding approximation. The ground miniband width and the longitudinal effective mass have been computed, for the electrons, versus the Zn composition and the interquantum dot separation as well. An analysis of the results shows that the Zn compositions x = 0.4 and x = 0.6 are appropriate to give rise a superlattice behavior for conduction electrons in a range of inter-sheet separations studied.

Today, various kinds of pressure garments are designed for specific applications in medical and sports fields. Knitted garments are the most used in these applications due to their high extensibility. The objective of the investigation reported in this article was to develop a theoretical relationship based on Laplace’s law, which describes the compression behavior of knitted compression samples in quasi-static deformation from an initially relaxed state to an extended state. Even though several researchers have used Laplace’s law, there is some discord between theoretical and experimental results. So, it is essential to pinpoint the most important parameters that influence the mechanical properties of the compression knitted garment in order to better describe the interface pressure it applies to the human body. Fabric parameters that influenced the interface pressure, such as elasticity modulus, strain, and thickness, were determined and integrated into Laplace’s law.

This work reports on a theoretical study of superlattices based on Cd 1-x Zn x S quantum dots embedded in an insulating material. This system, assumed to a series of flattened cylindrical quantum dots with a finite barrier at the boundary, is studied using the tight binding approximation. The electronic states of  1 Γ miniband have been computed as a function of zinc composition for different inter-quantum dot separations. Calculations have been made for electrons, heavy holes and light holes. Three main features were revealed: (i) in the case of electrons, the Zn composition x = 0.4 is expected to be the most favorable to give rise a superlattice behavior for the Cd 1-x Zn x S quantum dots studied (ii) the strong localization character of heavy holes is evident in the Cd 1-x Zn x S nanostructures (iii) the Cd 0.2 Zn 0.8 S system is the more appropriate to exhibit a superlattice behavior for light holes especially when the superlattice period is low.

As for the heavy holes, it has been showed the strong localization character of theses carriers in the Cd 1-x Zn x S nanostructures.
