By a News Reporter-Staff News Editor at Science Letter -- Current study results on Silicon have been published. According to news reporting originating in Shanghai, People's Republic of China, by NewsRx journalists, research stated, "Si-doped diamond films with various Si concentrations are deposited on WC-Co substrates using HFCVD method, with the mixture of acetone, tetraethoxysilane (TEOS) and hydrogen as the reactant source. A variety of characterizations, including FE-SEM, AFM, Raman, XRD, surface profilometer and Rockwell indentation, are conducted to systematically investigate the influence of Si incorporation on diamond films."
The news reporters obtained a quote from the research from Shanghai Jiao-Tong University, "As the Si/C ratio from 0% to 5%, the grain size of as-deposited films decreases from 4 mu m to about 50 nm, and the surface roughness reduces from Ra similar to 290 nm to Ra similar to 180 nm. Besides, the intensity ratio of I(111)/I(220) varies from 0.57 to 0, indicating the < 110 > preferred orientation of the nanocrystalline structure in the 5% doped diamond films. The silicon doping is beneficial for the formation of non-diamond carbide phases in the films, according to the Raman spectra."
According to the news reporters, the research concluded: "Moreover, the film adhesion is also improved with the increase of Si/C ratio."
