There are several methods for synthesizing semiconductor nanocrystals, including colloidal synthesis, chemical vapor deposition (CVD), and molecular beam epitaxy (MBE). Colloidal synthesis is one of the most common methods due to its simplicity and ability to produce high-quality nanocrystals in large quantities. This method involves the reaction of precursors in a solution, followed by the nucleation and growth of nanocrystals.
