Design of enhanced sensitivity gas sensors by using 1D defect ternary photonic band gap structures

In this paper, an approach to design enhanced sensitivity gas sensors by using one-dimensional (1D) defect ternary photonic band gap (PBG) material structure is demonstrated. It is shown that when the 1D defect binary PBG structure gas sensors are modified to 1D defect ternary PBG structure gas sensors, the sensitivity of the sensor enhances by 100%. Thus, by converting 1D defect binary PBG structures to 1D defect ternary PBG structures enhanced sensitivity gas sensors can be fabricated.
