Abstract

Abstract: 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. Abstract : Biphasic, multifunctional nanocomposites can be formed by (i) plasma synthesis of nanocrystals, (ii) their supersonic deposition, and (iii) infilling voids in the nanocrystal films with a second phase via atomic layer deposition. This paper describes recent efforts in the synthesis and characterization of these materials and provides a perspective for optimizing their electronic, thermal, and optical properties.
