Figure 3

Calculated reflectance response for the (a) aGST phase and (b) cGST phase of GST in the absence of HfO2 material. The layered structure formed in this response is analyte–Ag–Si–GST–Si. In addition, a proposed quadratic equation for determining the sensitivity across a given range of refractive index and wavelength is shown by the E1–E18 traces.
