In the increasing need for miniaturization of microelectronics and increasing computing speed, there are challenges such as increased heat dissipation, cross-talk (interference) and increasing cost. There is a push towards using silicon-based systems due in part to its low cost, abundancy, compatibility and non-toxicity. The surface chemistry of silicon is also very well-known and therefore it can easily be functionalized to tailor for specific applications.

University of Alberta researchers have created a method to deposit silicon nanocrystals (Si-NCs) inside microcavities to develop a high quality fluorescent optical resonator. The technique is simple, inexpensive and reproducible. Applications of the device include the development of a silicon-based laser and optical microfluidic sensors for biochemical sensing. There may also be applications to the display industry.
