Abstract:
Due to the large band gap, high charge-carrier mobility, high exciton binding energy, low toxicity, high thermal and radiation stability, zinc oxide is considered as a promising material for fabrication gas detectors, sensors of ultraviolet light, electroluminescence devices. Furthermore, chemically deposited ZnO films are widely used as conductive and optical cover layers of solar cells. Among the various methods of ZnO thin films obtaining, chemical bath deposition is one of the promising non-vacuum method of synthesis of layers with controllable structural and electrophysical properties.

Abstract:
Semiconductor devices are commonplace in every household. One application of semiconductors in particular, namely solid state lighting technology, is destined for a bright future. To this end, ZnO nanostructures have gained substantial interest in the research community, in part because of its requisite large direct band gap. Furthermore, the stability of the exciton (binding energy 60 meV) in this material, can lead to lasing action based on exciton recombination and possibly exciton interaction, even above room temperature. Therefore, it is very important to realize controllable growth of Zn

Abstract:
ZnO1-хSx alloys have attracted a special interest of researchers due to the possibility of controlled change of the band gap in a wide range from 3.37 eV (ZnO) to 3.68 eV (ZnS). This allows creating of effective UV photodetectors, electroluminescent devices, and others. The use of ZnO1-хSx buffer layers instead of ZnO can increase the conversion efficiency of thin-film solar cells based on CdTe, Cu(In, Ga)Se2 and Cu2ZnSnS4.

The buffer layer is a crucial component in thin film solar cells. Defects at the interface between absorber and buffer layer lead to high recombination rate and the band structure at the interface highly affects the performance of the solar cell.

A higher current from the device is expected when replacing the common buffer layer cadmium sulfide, CdS, with the more transparent CdZnS. It is also possible that the alternative buffer provides a

Chemical bath deposition (CBD) is the analog in liquid phase of the well-known chemical vapor deposition technique in the vapor phase.

Among all techniques used to grow Group II-VI semiconductors, CBD has the advantage of being a simple, low temperature, and inexpensive large-area deposition technique.

First, a chemical-bath deposited (CBD)ZnS thin film was prepared on sapphire substrate. Then, the ZnO was grown by pulsed laser deposition (PLD) on the CBD-ZnS at a substrate temperature of 900 ?C. When the substrate temperature was increased to 900 ?C, the ZnS film can be decomposed to Zn nanoparticles and sulfur fumes. The sulfur fumes were exhausted; meanwhile, Zn nanoparticles were formed on sapphire. The formation of Zn nanoparticles with the hexa
