Mathematical Modeling and Optimization of the Process of Formation of Functional Thin MoSe2 Films

摘要

Abstract This paper considers mathematical modeling and optimization of the technological process for obtaining functional Mo-Se thin films by the electrochemical method. The study is carried out by potentiodynamic, potentiostatic, and galvanostatic methods, under various conditions on Pt and Ni electrodes. The mathematical calculations are performed in a software package using software specially developed for this process. The optimal electrolysis mode and electrolyte composition for the codeposition process are chosen by studying the effects of various factors (the concentration of the initial components, temperature, current density, etc.). A statistical analysis of the resulting regression equation is carried out, the average approximation error is calculated, and the standard deviation is estimated. To evaluate the constructed multiple regression equation, Fisher’s test is calculated and the regression coefficients are estimated. The resulting regression equation determines the electrolyte content and electrolysis conditions, which allows the deposition of the Mo-Se alloy containing the required amount of Mo.
