Table 1 Shows the values of the sensitivity (S), quality factor (QF), figure of merit (FOM), signal-to-noise ratio (SNR), detection limit (δn), and sensor resolution (SR) by increasing the glycerin central defect thickness Ddef from 500 to 1000 nm, at an incident angle θ = 0º, GaN thickness dA = 100 nm, air thickness dB = 200 nm and number GaN/air of periods N = 3 with identification the temperature range, wavelength range and shift direction of each thickness.
