The controlled synthesis of CNs is the primary step to exploiting its size-specific properties; the hot injection (HI) method is one of the most common methods. CNs are synthesized by degassing, injection, and quenching.
During the synthesis, ligands play a crucial role as their nonpolar property allow colloidal stability, control the addition and removal of atoms, and permit fine crystal growth. Different from single-component nanocrystals, heterostructures nanocrystals are synthesized for their carrier behaviors and optical and electrical properties.
Zinc blended CdSe nanoplatelets and anisotropic quantum rods synthesized from molecular beam epitaxy and HI are examples of shape-controlled CNs.
Understanding CNs' electronic properties can help to design sophisticated devices.
CNs are examined using X-ray photoemission spectroscopy, which is also used to identify CNs’ types and modify their energy spectrum.
Field-effect transistor (FET) configurations examine the properties of nanocrystal solids and give insights into the majority carriers’ nature and the carriers’ mobility in the nanocrystal solids.
