Semiconductor oxides are used in electronics, optics, catalysts, sensors and other functional devices. In their 2D form they gain exceptional properties, useful for creating faster electronics and more efficient catalysts. Nanostructured semiconductor oxides for the next generation of electronics and functional devices examines the development of semiconductor nano-crystals and their applications, including energy harvesting, solar cells, solid oxide fuel cells and chemical sensors. The book addresses the structural and chemical modification of semiconductor nanocrystals during material growth. It then covers their use in nanoscale functional devices, particularly in electronic devices and carbon nanotubes. The impact of 2D nano-crystals including graphene, chalcogenides and oxide nanostructures on research and technology is explored, leading to a discussion of incorporating graphene and semiconductor nano-structures into composites for use in energy storage. The author then considers their uses in photovoltaic cells, in solid oxide fuel cells and in environmental sensors.
