The samples were annealed at different times and temperatures. The characterizations of the prepared PANI films were described by X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR). It is found that the conductivity changes under deep mouth exhaling for 150/1 h sample is 1.65 times faster than the films annealed at 100°C/4 h. The response and recovery time of the 150/1 h EDA-doped PANI film is decreased by order of 0.63 and 1.29 s than those films dried at 100°C for 4 h, respectively. The 150/1 h EDA doped PANI film during deep exhaling its conductivity increased abruptly from 2.2 × 10–7 to 0.026 S/cm–1. In a few seconds, following an inhalation, there occurs a complete transition to the dry state conductivity. Furthermore, the increment in conductivity of the EDA-doped PANI films was determined at various RH levels (20, 40, 60, 80, and 90%) with exposure and evacuation of the humid air. The doped PANI sample annealed at 150°C for 1 h exhibit the highest conductivity at 90% RH. The conductivity was increased from 2.16 × 10–7 S/cm for the insulating state at the dry state to 0.23 S/cm for the semiconducting state at 90% RH. Consequently, the 150/1 h sample showed an increase in conductivity by order of 106 at 90% RH. For all samples, the conductivity progressively rises as the RH value increases till 90% of RH value samples exhibit an abrupt increase in conductivity except the 100°C/4 h sample. The highest conductivity is 0.041 S/cm at 90% RH obtained for the case of 150/30 min sample, whereas the 150/1 min and 100/4 h films show maximum conductivity of 0.027 and 0.007, respectively.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"66 11","pages":"505 - 515"},"PeriodicalIF":0.9,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigate a one-dimensional Fibonacci quasiperiodic structure, consisting of periodic waveguides with resonators of varying lengths that depend on each other according to a Fibonacci sequence, attached to N evenly spaced sites. Our research reveals that the photonic bandgap of this structure is significantly influenced by the first two Fibonacci states, d2in and d21. Additionally, by introducing geometric defects at the resonators level, we enhance the structure’s ability to generate new permissible states within these gaps. The remarkably narrow width of these gaps confines defect modes to a very low-frequency range. Consequently, these defect modes emerge as distinct peaks in the transmission spectrum with optimal transmission and a very high-quality factor. Our results not only shed light on the core characteristics of photonic bandgaps, but also open up new possibilities for their practical use in telecommunications.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"66 11","pages":"489 - 496"},"PeriodicalIF":0.9,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
