Abstract

A large conglomerate of silicon atoms is known to group together forming a silicon nanocluster. Through quantum confinement effects, these silicon nanoclusters are known to luminesce when they are grown to a critical radius. Luminescence may have applications ranging from data transmission over wireless networks, to building low cost biomedical lasers, and to effectively eliminating the bandwidth of a signal inside of a silicon chip, hence it is a worthwhile research interest. This critical radius was modeled as a function of the concentration of excess silicon originally embedded in a silicon dioxide film. Using a simplified diffusional approach, the theoretical size, growth and pacification of nanoclusters were compared to experimentally confirmed results. Processing techniques that may allow for the growth of such a film were examined, and an American company called Veeco was found that could accommodate such a process.
