文摘

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