AB  - One-dimensional photonic crystal (1DPC) sensors have emerged as contenders for 
      traditional surface plasmon resonance sensors, owing to their potential for the 
      detection of bigger molecules and particles due to their higher interaction 
      volume in the sensing medium. Two-dimensional layered nanomaterials, most notably 
      graphene and dichalcogenides (e.g., MoS(2), MoSe(2), WS(2), and WSe(2)), have shown 
      higher refractive index sensitivity because of their absorption as well as 
      adsorption property. The proposed configuration of 1DPC presented consists of 
      alternate layers of the aforementioned nanomaterials and silicon. The performance 
      parameters, namely the sensitivity, resolution, quality factor, and the 
      evanescent field penetration depth, are calculated and compared with 1DPC having 
      poly methyl methacrylate (PMMA) in place of silicon. Increased shift in resonance 
      angle and quality factor are observed by replacing PMMA with silicon, but at the 
      cost of decreased resolution. Further, our results show that although the 
      sensitivity and quality factor of the 1DPC sensor is less than that of the 
      conventional surface plasmon resonance sensor (SPR) with a gold thin film, it has 
      much higher resolution and penetration depth to make it suitable for large 
      molecules.
