The films were post-annealed at 700, 900, and 1100°C for 2 h, then the crystal structure, surface morphology and optical properties of the films were studied. As the post-annealing temperature increases, the average crystallite size of the film increased from approximately 6 to 21 nm, and the FWHM of rocking curve for the (400) plane of the β‑Ga2O3 decreased from 1.29° to 0.38°. The increase of post-annealing temperature controls phase formation in the films. When post-annealed at 700°C, the Ga2O3 film is not completely transformed into β phase. While post-annealed at temperatures ≥900°C, the Ga2O3 in the films is all β-Ga2O3. Additionally, the increase in post-annealing temperature induced changes in the micro-strains of Ga2O3 films, which resulted in a reduction of the bandgap. These findings highlight the critical role of post-annealing temperature in controlling the structural and optical properties of Ga2O3 thin films, making it a key parameter for improving the quality of β-Ga2O3 films.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"67 5","pages":"331 - 337"},"PeriodicalIF":0.9,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938665","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}

The electronic device density of states (DDOS) of the hydrogen-passivated zigzag GNR (w = 8) proves its metallic behavior with Van Hove Singularity (VHS). The values of transmission spectra were calculated using an applied voltage of 1, 2, 3, and 4 V. Moreover, the hydrogen-passivated zigzag GNR device shows a steady current increase from 0 to 21 000 nA with voltage, featuring a plateau between 2.7 and 2.8 V. When an EMF is applied perpendicular to the ribbon plane, there is minimal optical absorption in the graphene nanoribbon due to the lack of direct interaction between the field and electrons as well. However, along the nanoribbon, fluctuations in the EMF induce transitions between electronic states and lead to optical absorption. The z polarization of the incident light results in enhanced absorption in this direction, mainly due to the localized edge states of the GNR. Therefore, the peak optical absorption occurs in the y direction.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"67 5","pages":"367 - 372"},"PeriodicalIF":0.9,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938666","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}

X-ray diffraction (XRD) and Rietveld refinement analyses confirmed that doping of Eu3+ ion significantly affects the structure of the Ti–O6 polyhedra, which in turn influenced their dielectric properties. Impedance spectroscopy revealed that both grain and grain boundary contributions significantly impact the overall conductivity of the Eu-doped CCTO, with the grain boundary resistance dominating at lower temperatures. The high activation energies associated with grain boundaries suggest the presence of a Schottky barrier potential, which likely contributes to reducing the dielectric loss in the material. Scaling analysis provided insights into the relaxation mechanisms associated with grains and grain boundaries, revealing distinct relaxation zones and highlighting the anisotropic nature of charge distribution at grain boundaries. Overall, the study confirms that Eu doping in CCTO ceramics enhances their dielectric properties by influencing structure of the host matrix as well as grain interior and grain boundary characteristics. These findings offer critical insights into the material’s behavior and present opportunities for optimizing CCTO-based ceramics for advanced high-performance electronic applications.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"67 5","pages":"413 - 421"},"PeriodicalIF":0.9,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938423","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}
