Summary: | The invention discloses a defective quasi-periodic photonic crystal structure for enhancing GH displacement. The defective quasi-periodic photonic crystal structure is a mixed structure formed by combining four media with different refractive indexes according to an arrangement rule, the arrangement rule is defined as follows: a symmetrical medium structure positioned in the middle and quasi-periodic photonic crystal structures positioned on two sides of the symmetrical medium structure; wherein the symmetrical medium structure is composed of a single layer of MoS2 and two layers of HfO2 which are symmetrically distributed on the two sides of the single layer of MoS2; and the quasi-periodic photonic crystal structures are formed by alternately distributing Li2O layers and Si layers which take a Pell sequence as a template, and the quasi-periodic photonic crystal structures on the two sides are respectively superposed in a period N and a period M. According to the structure, a single layer of MoS2 is clamped b |
