Surface plasmon resonance (SPR) sensor based on the blue phosphorene/MoS2 hetero-structure is presented to enhance the performance parameters,i.e.,sensitivity,detection accuracy,and quality factor.The blue phosphorene/MoS2 hetero-structure works as an interacting layer with the analyte for the enhancement of the sensitivity of the sensor.It is observed that the sensitivity of blue phosphorene/MoS2 based sensor (i.e.,structure-Ⅱ) is improved by 5.75％,from the conventional sensor (i.e.,structure-Ⅲ).Further,an additional silicon nanolayer is introduced between the metal layer and blue phosphorene/MoS2 hetero-structure.The sensitivity of the proposed blue phosphorene/MoS2 hetero-structure with a silicon layer SPR sensor,i.e.,structure-Ⅰ,is enhanced by 44.76％ from structure-Ⅱ and 55.75％ from structure-Ⅲ due to an enhancement in the evanescent field near the metal-analyte interface.Finally,it is observed that at the optimum thickness of silicon between the gold layer and blue phosphorene/MoS2,performance parameters of the sensor are enhanced.
