electric potential distribution near nanocone arrays on metal substrates

Chinese Physics B 2012年第5期21卷 636-640页

作者：黄晓菁游荣义 Department of Physics School of ScienceJimei University

Based on the nanostructured surface model,where conical nanoparticle arrays grow out symmetrically from a plane metal substrate,a theoretical model of the local electric potential near nanocones is built when a uniform external electric field is *** terms of this model,the electric potential distribution near the nanocone arrays is obtained and given by a curved surface using a numerical computation *** computational results show that the electric potential distribution near the nanocone arrays exhibit an obvious geometrical *** results could serve as a basis for explaining many abnormal phenomena,such as the abnormal infrared effects（AIREs） which are found on nanostructured metal surfaces,as well as a reference for investigating the applications of nanomaterials,such as nanoelectrodes and nanosensors.
