摘　　要：研究了单锥纳米孔的整流效应与纳米孔结构参数之间的关系。单锥纳米孔的整流比与KCl溶液的浓度密切相关。在浓度为0.01~1000 mol/m^3范围内,整流比先增加后减小,在浓度为0.1 mol/m^3时达到最大。随着纳米孔长度的增加,单锥纳米孔在浓度为0.1 mol/m^3时的整流比(Rf_0.1)逐渐增加。在纳米孔尖端直径为25~400 nm的范围内,Rf_0.1呈现出先增加后减小的趋势。随着纳米孔半锥角在6°~24°逐渐增加,Rf_0.1是逐渐减小的。Relationship between the rectification effect and structural parameters of single conical nanopores is studied.The rectification ratio of single-conical nanopore is closely related to the concentration of KCl solution.When the concentration changes within 0.01~1000 mol/m^3,the rectification ratio increases firstly and then decreases,reaching the maximum at the concentration of 0.1 mol/m^3(Rf_0.1).With the increase of the length of nanopore,the rectification ratio of the single conical nanopore increases gradually when the concentration is 0.1 mol/m^3.Rf_0.1 increases firstly and then decreases as the increase of nanopore tip diameter in 25~400 nm.Rf_0.1 decreases with the increase of the half conical angle from 6°to 24°.
