ABSTRACT
ZnO is an important II-VI semiconductor, which have been extensively studied in photovoltaics, photoelectrochemical cells, piezoelectric nanogenerators (NGs), ultraviolet detectors, lasers, light-emitting diodes, and gas sensors, due to its unique optical and electrical properties including wide bandgap, higher excitonic binding energy, superior electron mobility, low cost, and environmental friendliness. ZnO-polymer nanocomposites are especially interesting due to their control particle size and high stability. The influence of polymer matrix plays a major role in the optical and electrical properties of the composite materials. In recent years, significant progress has been made in the synthesis of various types of ZnO-polymer nanocomposites for the fabrication of electronic and optoelectronic devices. Particularly, ZnO nanostructures embedded or encapsulated in the insulating polymer matrix are attractive for high dielectric materials, memory devices, gas sensors, piezoelectric NGs, and photosensing applications. Here, we discuss the growth and characteristics of ZnO nanostructure-insulating polymer dielectric thin films and their device applications.
