Functionalised zinc oxide nanowire gas sensors: Enhanced NO2 gas sensor response by chemical modification of nanowire surfaces
Surface coating with an organic self-assembled monolayer (SAM) can enhance surface reactions or the absorption of specific gases and hence improve the response of a metal oxide (MOx) sensor toward particular target gases in the environment. In this study the effect of an adsorbed organic layer on the dynamic response of zinc oxide nanowire gas sensors was investigated. The effect of ZnO surface...
متن کاملFace-selective electrostatic control of hydrothermal zinc oxide nanowire synthesis.
Rational control over the morphology and the functional properties of inorganic nanostructures has been a long-standing goal in the development of bottom-up device fabrication processes. We report that the geometry of hydrothermally grown zinc oxide nanowires can be tuned from platelets to needles, covering more than three orders of magnitude in aspect ratio (~0.1-100). We introduce a classical...
متن کاملPiezoelectric nanogenerators based on zinc oxide nanowire arrays.
We have converted nanoscale mechanical energy into electrical energy by means of piezoelectric zinc oxide nanowire (NW) arrays. The aligned NWs are deflected with a conductive atomic force microscope tip in contact mode. The coupling of piezoelectric and semiconducting properties in zinc oxide creates a strain field and charge separation across the NW as a result of its bending. The rectifying ...
متن کاملField emission properties of individual zinc oxide nanowire field emitter
The authors report the field emission FE properties of individual ZnO nanowire field emitters. ZnO nanowire field emitter directly grown on a Pt tip showed a much better field emission current delivery than the attached nanowire emitters due to better contact properties. The emission current and field emission microscopy pattern of the ZnO nanowire are strongly influenced by adsorbates. After t...
