The electronic transport properties of ternary Cd(1-x)Zn(x)S nanowire networks

Compositional variation dependent colour tuning and observation of Förster resonant energy transfer in Cd(1−x)ZnxS nanomaterials

Energy level diagram of FRET process in Cd_(1−x)Zn_xS nanomaterials between donor (ZnS) and acceptor (CdS): the smaller ZnS materials transfer energy nonradiatively to the larger CdS materials when there is sufficient spectral overlap between them.

Giant UV-sensitivity of ion beam irradiated nanocrystalline CdS thin films

A highly sensitive UV-detector is devised for the first time from ion beam irradiated nanocrystalline CdS thin films. The sensor exhibits improvements in the responsivity, photosensitivity, and efficiency as a function of ion fluence.

CdS nanoscale photodetectors

CdS nanostructures have received much attention in recent years as building blocks for optoelectronic devices due to their unique physical and chemical properties. This progress report provides an overview of recent research about rational design of CdS nanoscale photodetectors. Three kinds of photodetectors according to the metal-semiconductor contact types are discussed in detail: Ohmic contact, Schottky contact, and field enhanced transistor configuration. The focus is on the tuning of optical and electrical properties CdS nanostructures by element doping, composition and bandgap engineering, and heterojunction integration, along with thus modified device performances generated during these tuning processes. Latest concepts of photodetector design such as flexible, self-powered, plasmonic, and piezophototronic photodetectors with novel properties are introduced to demonstrate the future directions of such an exciting research field.
