Hybrid Mode Based Ultrasensitive Nanohole Array Bio-Sensor

Abstract

A nanohole array based bio-sensor has been achieved numerically. The nanohole array is arranged in a hexagonal lattice and the material of the metal film is aluminum. With optimized parameters, the figure of merit of the presented nanohole array based sensor is around 169 which has surpassed the reported figure of merit of nanohole array based sensors.
