Texturing of Indium Phosphide for Improving the Characteristics of Space Solar Cells
This paper discusses and demonstrates the usefulness and prospects of using textured layers of indium phosphide as a material for space solar cells. Such designs improve the performance of the photovoltaic converter by increasing the effective area and surface roughness. Thus, it minimizes the background reflectivity of the surface. Textured layers on the InP surface were obtained by electrochemical etching using a bromous acid solution.
Investigation of Critical Points of Pore Formation Voltage on the Surface of Semiconductors of A3B5 Group
In this work, critical values of pore-formation in electrochemical machining of semiconductors of A 3 B 5 group are studied. On the example of indium phosphide, the indicators of the series of dependence of current density on the voltage of anodization are studied. The rates of current density increase in the regime of gradual rise of anodization voltage are determined. According to these indicators, the intervals are established, within which the active pore-formation occurs on the surface of semiconductor.
Morphology Study of the Porosity of the GaP Surface Layer Formed on the Surface of a Single Crystal by Electrochemical Etching
The article analyzes the morphological characteristics of a porous GaP surface layer formed on the surface of monocrystalline gallium phosphide by electrochemical etching. The correlations between the etching time and the appropriate size, shape and density of pores have been established and studied in detail.
Nanostructure Formation on ZnSe Crystal Surface by Electrochemical Etching
The article describes a simple method for nanostructuring the surface of monocrystalline zinc selenide. It is shown that the traditional electrochemical etching of n-ZnSe (111) samples in a concentrated solution of nitric acid leads to the appearance of massive etching pits and small pores on the surface. The dynamics of the process and stages of crystal dissolution has been studied. It is assumed that the porous zinc selenide obtained in this way can be used in optoelectronic structures, as well as as buffer layers for growing zinc oxide.
