Calculated reflectance response for the different heights of material layers. Reflectance variation for different height values of the (a) GST, (c) silica, and (e) HfO2 for the aGST phase of the phase change material. Reflectance variation for different height values of the (b) GST, (d) silica, and (f) HfO2 for the cGST phase of the phase change material.
