New Findings from Northwestern Polytechnic University in Condensed Matter Provides New Insights (Effect of radio frequency power on composition, structure and optical properties of MoSex thin films)

By a News Reporter-Staff News Editor at Physics Week -- Research findings on Condensed Matter are discussed in a new report. According to news reporting from Shaanxi, People's Republic of China, by VerticalNews journalists, research stated, "MoSex films were prepared by radio frequency (RE) magnetron sputtering under various RE powers in the range of 40-130 W. Effects of RE power on composition, structure and optical properties of MoSex films were investigated. Results show that the chemical bonding, binding energy, structure, and optical properties of MoSex films depend greatly on RF power."

The news correspondents obtained a quote from the research from Northwestern Polytechnic University, "When the RF power varies from 40 to 70 W, the bonding atomic ratio of Se/Mo in MoSex films increase and Mo 3d(5/2) and Se 3d(5/2) peaks shift towards lower binding energies. With further increase in the RF power from 70 to 130W, the bonding atomic ratio of Se/Mo in MoSex films decreases and Mo 3d(5/2) and Se 3d(5/2) peaks move to higher binding energies."

According to the news reporters, the research concluded: "Structures of MoSex films are amorphous with the RF power 70W, Moreover, MoSex films deposited at 70W have larger refractive index, lower extinction coefficient, and higher band gap than those deposited at other RE power."
