Table 4 Shows the values of the parameters sensitivity (S), quality factor (QF), figure of merit (FOM), signal-to-noise ratio (SNR), detection limit (δn), and sensor resolution (SR) at different thickness of GaN (dA) from100 to 900 nm, the air thickness dB = 200 nm, the incident angle θ = 65º, number of GaN/air periods N = 3 and the defect thickness Ddef = 900 nm with identification the temperature range, wavelength range and shift direction for each thickness.
