One-dimensional CdS nanostructures: synthesis, properties, and applications

Abstract

One-dimensional (1D) semiconductor nanostructures are of prime interest due to their potential in investigating the size and dimensionality dependence of the materials' physical properties and constructing nanoscale electronic and optoelectronic devices. Cadmium sulfide (CdS) is an important semiconductor compound of the II-VI group, and its synthesis and properties have been of growing interest owing to prominent applications in several fields. This article provides a comprehensive review of the state-of-the-art research activities that focus on the rational synthesis, novel properties and unique applications of 1D CdS nanostructures in nanotechnology. It begins with the rational design and synthesis of 1D CdS nanostructures, and then highlights a range of unique properties and applications (e.g. photoluminescence, cathodoluminescence, electrochemiluminescence, photocatalysis, lasers, waveguides, modulators, solar cells, field-effect transistors, photodetectors, field-emitters, and nanogenerators) associated with them. Finally, the review is concluded with the author outlook of the perspectives with respect to future research on 1D CdS nanostructures.

Containing the catalyst: diameter controlled Ge nanowire growth

“…2,[5][6][7][8] Recently, supercritical uid (SCF) growth methods have enabled the large scale production of Si and Ge nanowires in a robust, relatively inexpensive manner. 9 Various templated growth methods have been employed for growing small diameter Ge nanowires (<15 nm), including the use of anodic alumina oxide and silica membranes. [10][11][12][13] The high-diffusivity of a supercritical uid enables rapid transport of precursors into the pores of many templates, permitting swi nucleation and growth of nanowires.…”
