In recent years, the understanding of processes on material surfaces has drawn considerable interest from scientists. The adsorption stage is important for further insights into surface interactions and photocatalytic reactions. In this study, we use density functional theory computations to investigate the adsorption of sulfamethoxazole (SMX) molecules on the rutile-TiO2 (001) surface (r-TiO2 ).

This study aims to contribute to the development of a GaN/Ga2O3 diode that can be utilized in high-power device applications. The simulated device is calibrated against experimental GaN and Ga2O3 diodes, considering the effect of thickness of GaN layer and its doping concentration on the performance of GaN/Ga2O3 diodes. The band structures of devices are investigated to revial which factors that affect the properties of GaN/Ga2O3 diode.

The study which applies quantitative methods along with the support of EVIEWS software points out a statistical significance relationship. Firstly, the CS has a contrariwise impact on ROA but no effect on ROE and ROS. Secondly, among control variables (asset structure, expenditure ratio, revenue), the expenditure ratio is the only one showing a contrariwise impact on ROS and the rest has no statistical significance.
