Structural and optical characteristics of ZnSe and CdSe films condensed on non-oriented substrates

In this work, the complex investigation of structural and optical properties of zinc and cadmium selenide semiconductor films deposited by close-spaced vacuum sublimation method using thermal evaporation on non-oriented substrates was carried out. The structural and phase analyses of the layers condensed at different substrate temperatures were performed. The transmission and reflection spectra of the investigated films have been measured and their main optical characteristics have been calculated

Substructural Features of Zn1-xMnxTe Solid Solution Thin Films

The substructural characteristics of Zn1-xMnxTe films deposited by closed space vacuum sublimation method under various condensation conditions are investigated. Sizes of the coherent scattering domain size, microdeformation degree, staking fault defects’ concentration in the condensates, the averaged dislocation density at the subgrain boundaries and in their bulk as well as the total dislocation concentration are determined by the physical broadening of the X-ray lines using the Cauchy and gauss approximations and the threefold function convolution method. The calculations are compared with data for undoped ZnTe. It is found out that the Mn-doping causes some degradation of structural characteristics of the condensates compared with undoped layers.

Structural Properties of ZnO Thin Films Obtained by Chemical Bath Deposition Technique

Zinc oxide thin films have been deposited onto glass substrate from zinc sulfate, ammonia and thiourea aqueous solution by chemical bath deposition. In the work this were specified solution preparation procedure and optimized the composition of the solution and content of component in it. X-ray difraction and high-resolution scanning electron microscopy were used to characterize structure formation of obtaining ZnO films. As a result of investigation was determined the effect of time deposition on the structural and substructural properties such as lattice parameters, texture quality, coherent scattering domain size.
