This video shows how silicon nanocrystals are synthesized in a plasma reactor. Inert argon gas flows from the top of the reactor through a glass tube. Fifteen watts of radio frequency power is applied to the copper ring electrodes to ionize the argon gas and produce what is called a plasma. A gas containing silicon (silane) is injected into the reactive plasma environment to produce silicon nanocrystals. Though the plasma is energetic enough to produce these tiny crystals, the glass tube remains cool enough to touch. The plasma is a reactive environment used to produce silicon nanocrystals that can be applied to inexpensive, next-generation electronics.
