• the Si substrate, the oxygen content contains contributions from both SiO2 and ZnO. The variations in grain size and RMS roughness of ZnO films with increase in ion fluence follow the same trend in AFM and FESEM analyses, but with different magnitudes. This is because of the greater sensitivity of AFM

• thickness. The optical constants (i.e., the refractive index n, the extinction coefficient k, and the absorption coefficient α) of the SiO2 and ZnO oxide films were determined from the transmission spectra recorded in the range of 190–2500 nm by using the Swanepoel method, while the energy bandgap was

• ; optical quality; SiO2 and ZnO; structural properties; thin films; Introduction The application of oxide thin films is quite diverse due to their excellent properties [1][2][3][4][5], such as dielectric properties [6][7][8] for the production of metamaterials [9]. Metamaterials applied in the field of

The analysis of the journals that contributed to the database revealed that more than half of the relevant papers originated from seven journals: Environmental Toxicology and Chemistry (29
