Mathematical modeling and optimization of the process of formation of functional thin MoSe$_2$ films

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