NANOPARTICLE INKS BASED ON SILICON/GERMANIUM, DOPED PARTICLES, PRINTING AND PROCESSES FOR SEMICONDUCTOR APPLICATIONS

摘要

Highly uniform silicon/germanium nanoparticles can be formed into stable dispersions with a desirable small secondary particle size. The silicon/germanium particles can be surface modified to form the dispersions. The silicon/germanium nanoparticles can be doped to change the particle properties. The dispersions can be printed as an ink for appropriate/ applications. The dispersions can be used to form selectively doped deposits of semiconductor materials such as for the formation of photovoltaic cells or for the formation of printed electronic circuits.
