Nanocrystal-based inorganic nanocomposites: A new paradigm for plasma-produced optoelectronic thin films

Nanocrystal-based nanocomposites are biphasic materials with intriguing optoelectronic properties. They are formed through, first, plasma-synthesis of nanocrystals, followed by a second, supersonic impact deposition on translated substrates to form densely packed nanocrystal networks at high deposition rates. Third, dense nanocomposites are formed by subsequent infilling of the voids in the nanocrystal networks with a second phase matrix material using thermal- or plasma-enhanced atomic layer deposition. This paper reviews recent efforts to achieve excellent electronic transport in these nanocomposites. It then provides a perspective on how the biphasic nature of these materials can be used to independently control several materials properties and endow materials with multiple functionalities.
