Modeling and Performance Analysis of an Advanced Hybrid Surface Plasmon Resonance (SPR) Sensor Employing Indium Tin Oxide-Phosphorene Hetero Structure

A highly sensitive surface plasmon resonance (SPR) sensor employing ITO (indium tin oxide) as well as phosphorene is suggested with a hybrid structured design through comprehensive numerical simulations as a hopeful optical approach used in a wide range of applications across a diverse range of boundaries is suggested in this paper. The broadly utilized transfer matrix method (TMM) was employed to study and evaluate the suggested sensor performance. The figure of merit (FOM), sensitivity, reflectivity, and detection accuracy (DA) were all used to evaluate the sensor performance. In order to ameliorate performances, the sensor construction was enhanced by modifying several structural characteristics of the hybrid design. The results showed that putting ITO and phosphorene over the gold layer of the traditional construction increased the sensor performance with a topmost sensitivity of 238 deg/RIU and a FOM of 27.076 RIU-1. With such high detecting characteristics, the suggested sensor might be used in a variety of bio-sensing applications to identify liquid compounds or solutes that are biological and biochemical.
