Year: 2018

Type: article

Abstract: A surface plasmon resonance refractive index sensor based on MoS2-aluminium structure is designed for high imaging sensitivity and detection accuracy. The proposed sensor exhibits better performance than graphene-based refractive index sensor in the near-infrared regime. A high imaging sensitivity of more than 970 RIU-1is obtained at the wavelength of 1540 nm. The effect of aluminium thickness, number of MoS2layers, and the analyte refractive index on the sensor performance was investigated. In addition, the sensor performance comparison of MoS2and other two-dimensional transition metal dichalcogenide materials-based sensors in the near-infrared regime is also presented. The designed MoS2-based surface plasmon resonance refractive index sensor could provide potential applications in chemical and biological sensing.
