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 ...

Carrier density is one of the most important parameters in changing the electronic properties of materials. The most useful and conventional way to control the carrier density is chemical syntheses. On the other hand, physicists and electronic engineers have developed a field effect transistor (FET) device for changing the carrier density by electric fields. Furthermore, by introducing a liquid...

Fabrication of the strain-gated inverter (SGI) The SGI was fabricated by bonding two ZnO NWs laterally on a Dura-Lar film. The thickness of the Dura-Lar film is 0.5 mm. The ZnO NWs were synthesized via a physical vapor deposition method reported elsewhere [32] and typically have diameters of 300 nm and lengths of 400 μm (Fig. 1a). The films were first cleaned with acetone, isopropyl alcohol and...

A process methodology enabling the fabrication of various nanodevices is demonstrated that is compatible with standard integrated circuit processes and recently developed MEMS technologies. The basic devices are laterally suspended single-crystal silicon nanowires with diameters from ~20 nm formed by a single DRIE etch step and oxidation thinning cycles. These nanowires can further serve as mol...

Two-dimensional materials have various applications in the next generation nanodevices because of their easy fabrication and particular properties. In this work, we studied the effects of crystalline order on the magnetic properties of ultrathin MoS2 nanosheets. Results indicate that all the fabricated samples show clear room temperature ferromagnetism. The amorphous sample has the larger satur...

Nanoelectronic devices smaller than the electron wavelength can be achieved in graphene with current lithography techniques. Here we show that the electronic quantum transport of graphene subwavelength nanodevices presents deep analogies with subwavelength optics. We introduce the concept of electronic diffraction barrier to represent the effect of constrictions and the rich transport phenomena...

One-dimensional nanowires enable the realization of optical and electronic nanodevices that may find applications in energy conversion and storage systems. Herein, large-scale aligned DNA nanowires were crafted by flow-enabled self-assembly (FESA). The highly oriented and continuous DNA nanowires were then capitalized on either as a template to form metallic nanowires by exposing DNA nanowires ...
