Toward high output-power nanogenerator
(Georgia Institute of Technology, 2008-04-29)
In this paper, the factors that determine the power output of a piezoelectric nanowire (NW) nanogenerator (NG) have been analyzed. The output current is the sum of those contributed by all of the NWs while the output voltage ...
Depth resolved luminescence from oriented ZnO nanowires
(Georgia Institute of Technology, 2009-12-14)
We have utilized the limited penetration depth of x-rays to study the near-surface properties of vertically aligned ZnO nanowires. For an energy of 600 eV the penetration depth varies between 3 and 132 nm as the incidence ...
Gigantic enhancement in response and reset time of ZnO UV nanosensor by utilizing Schottky contact and surface functionalization
(Georgia Institute of Technology, 2009-05-11)
UV response of ZnO nanowire nanosensor has been studied under ambient condition. By utilizing Schottky contact instead of Ohmic contact in device fabrication, the UV sensitivity of the nanosensor has been improved by four ...
Effects of piezoelectric potential on the transport characteristics of metal-ZnO nanowire-metal field effect transistor
(Georgia Institute of Technology, 2009-06-05)
We have investigated the effects of piezoelectric potential in a ZnO nanowire on the transport characteristics of the nanowire based field effect transistor through numerical calculations and experimental observations. ...
Erratum: Effects of piezoelectric potential on the transport characteristics of metal-ZnO nanowire-metal field effect transistor

Growth and field-emission property of tungsten oxide nanotip arrays
(Georgia Institute of Technology, 2005-11-21)
Large-area, quasialigned nanotips of tungsten oxide have been grown by a two-step high-temperature, catalyst-free, physical evaporation deposition process. The tungsten oxide nanotips are single crystalline with growth ...
