ZnO tetrapods designed as multiterminal sensors to distinguish false responses and increase sensitivity

Nano Lett. 2008 Feb;8(2):652-5. doi: 10.1021/nl073088o. Epub 2008 Jan 25.

Abstract

Individual zinc oxide tetrapods were designed as multiterminal sensors by the e-beam lithography method. Different from double-terminal sensors, these sensors can give multiple responses to a single signal at the same time. The designed tetrapod devices were employed to detect light with different wavelength. The results indicate that they are remarkable optoelectronic devices, sensitive to ultraviolet light, and have advantages on distinguishing noises and increasing sensitivity. This should be helpful for weak signal measurements of nanodevices.
