Nanomaterials and Nanodevices

Nanoscience has been an emerging and rapidly expanding discipline in the past decade, which is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. Nanoscience and nanotechnology include three fields: nano-materials, nanodevices, and nanomeasurement and nano-characterization. This special issue mainly focuses on nano-ma...

Self-Replicating DNA Nanostructures: Autocatalytic Nanodevices derived from Catalytic Nanodevices

This paper describes some general techniques for transforming the design of a class of catalytic DNA nanodevices into the design for autocatalytic DNA nanodevices. Our techniques are particularly applicable to catalytic DNA nanodevices that act as detectors, where we would like their response to be sped up via autocatalytic behavior. We provide an example of this general scheme for design of au...

ZnO nanorods, heterostructures and nanodevices

One-dimensional nanorods open up many new device applications. As one of the semiconductor nanorods, ZnO-based nanorods have been studied for electronic and photonic nanodevice applications. Recently, we developed catalyst-free metal-organic chemical vapor deposition of ZnO nanorods and employed these ZnO nanorods for electrical and optical nanodevice applications. In this presentation, I will ...

Room-Temperature Ballistic Nanodevices

One of the most important physical parameters to describe the quality of a piece of semiconductor material is the electron scattering length le. Also referred to as the mean-free path, it stands for the average distance between the randomly distributed scatterers in the material, such as lattice defects, impurities, and phonons. The electron mean-free path is typically a few nanometers (1 nm = ...
