Figure 2

Reflectance response for the different (a) aGST phase and (b) cGST phase of the phase change material. The traces marked as P1 to P20 are the possible quadratic equation for identifying the sensitivity for the specific range of the refractive index and wavelength. The layered structure formed in this response is analyte–Ag–Si–HfO2–Si–GST–Si.
