An Optical Surface Profiler for Characterization of Surface Features

点击翻译按钮获取中文摘要

Thin films, coatings, and other surface layers are used for a variety of functional, decorative, and protective purpose in a myriad of applications including electronic, optical, photonic, sensor, aerospace, nuclear, and biomedical applications. Their surface characteristics and thickness are of paramount importance for the development of novel surfaces with much improved properties to meet the demand of rapid development of surface science and technology. The proposed Optical Surface Profiler will enable effective quantitative characterization of surface roughness, surface stress, thin film thickness, and wear depth in nanometer scale. Since there is no similar equipment existing in the University of Saskatchewan or elsewhere in the province, the acquisition of the instrument will have significant impact on the existing research programs related to surface science and engineering at the University of Saskatchewan. This research area is at the forefront of material science, and the instrument will help researchers make highly original contributions in the development of materials with much improved surface properties for various industrial and biomedical applications. The proposed equipment will also provide excellent opportunities for highly qualified trainees to gain practical experience and expertise in advanced surface science and technology.
