<div> Semiconductor oxides are already used for electronics, optics, catalysts, sensors and other functional devices; using them in their 2D form can alter their properties in beneficial ways, creating faster electronics and more efficient catalysts. The book begins by looking at the physics affecting nanostructured semiconductors, and goes on to address the structural and chemical modification of semiconductor nanocrystals during material growth. Chapters cover devices and functional structures based on nanostructured semiconductors, including electronics and optics, 2D semiconductors, and composite graphene-semiconductor nanostructures. Concluding chapters explore solar cells, solid oxide fuel cells and chemical sensors for environmental applications.</div>
