Table 6 Shows the Values of the parameters sensitivity (S), quality factor (Q), figure of merit (FOM), signal-to-noise ratio (SNR), detection limit (δn), and sensor resolution (SR) at different number of GaN/air periods from N = 4 to N = 6, at the condition GaN thickness dA = 100nm, air thickness dB = 200 nm, incident angle θ = 65º, and defect thickness Ddef = 900 nm with identification the temperature range, wavelength range and shift direction for each thickness.
