“…83,84 The alteration of the photonic bandgap of PhCs due to analyte gas at low concentration is the main challenge for the selective detection of analyte gas. 84,205–208 Therefore, maximum change of photonic bandgap by an analyte gas must be the primary concern in the fabrication of PhCs to improve selectivity. Recent experimental and theoretical demonstrations show that high sensitivity and high-quality factor can be achieved by using different PhC sensor configurations/sensors 209,210 e.g.…”

“…So far, the quasi-periodic structures in 1D and 2D PhCs have been achieved for both solid–solid and solid–fluid structures 28 , 30 . In quasi-periodic structures, band gaps with strong resonances peaks are also expected, which can strongly localize acoustic waves 31 . As a result, the quasi-periodic PhCs are promising candidates for overcoming the low-frequency limitations of large-scale acoustic structures 30 .…”

Ultra-sensitive greenhouse gas sensors for CO2, N2O, and CH4 gases based on Fano resonance modes have been observed through periodic and quasi-periodic phononic crystal structures. We introduced a novel composite based on metal/2D transition metal dichalcogenides (TMDs), namely; platinum/platinum disulfide (Pt/PtS2) composite materials. Our gas sensors were built based on the periodic and quasi-periodic phononic crystal structures of simple Fibonacci (F(5)) and generalized Fibonacci (FC(7, 1)) quasi-periodic phononic crystal structures. The FC(7, 1) structure represented the highest sensitivity for CO2, N2O, and CH4 gases compared to periodic and F(5) phononic crystal structures. Moreover, very sharp Fano resonance modes were observed for the first time in the investigated gas sensor structures, resulting in high Fano resonance frequency, novel sensitivity, quality factor, and figure of merit values for all gases. The FC(7, 1) quasi-periodic structure introduced the best layer sequences for ultra-sensitive phononic crystal greenhouse gas sensors. The highest sensitivity was introduced by FC(7, 1) quasiperiodic structure for the CH4 with a value of 2.059 (GHz/m.s−1). Further, the temperature effect on the position of Fano resonance modes introduced by FC(7, 1) quasi-periodic PhC gas sensor towards CH4 gas has been introduced in detail. The results show the highest sensitivity at 70 °C with a value of 13.3 (GHz/°C). Moreover, the highest Q and FOM recorded towards CH4 have values of 7809 and 78.1 (m.s−1)−1 respectively at 100 °C.
