2D Metal Oxide Nanosheets—Electronic Applications Recent Developments and Future Prospects

The emerging electronic applications of easily synthesized and quite stable metal oxide nanosheets have, particularly, been examined here in this chapter by going through various aspects of their general behaviors, syntheses, and characterization of their crystalline structures, and electronic conductivities in the form of mono-/multilayered thin films, superlattices, and nanocomposites; nano-tubules, spheres, shells, and cones to name a few. Basic study of these nanosheets in terms of charge carrier confinement, the presence of different excitons, electron–hole separations, and charge carrier transport across their heterostructures has been found very promising in exploring their electronic applications including sensors, energy harvesting and storage, especially in the form of lithium-ion and other batteries, photovoltaic solar cells (PVSCs), piezoelectric power generation, supercapacitors, photo-detectors, and nano-electronic/magnetic devices, followed by brief description of some of the recent applications reported.
