The laws of reflection and refraction represent the results of the momentum conservation, depending entirely on the specific wave nature of electromagnetic fields on an interface. However, material dispersion is a consequence of interaction of light with matter. The refractive index and material dispersion are determined by the plasma and resonance frequencies, which are the functions of temperature. These characters lead to the temperature-dependent refractive index and material dispersion. When an electromagnetic wave propagates through a dielectric medium, the motions of the charged particles are affected by the incident harmonic wave and thermal radiations of random phases. The plasma and resonance frequencies are related to the thermal oscillation frequency of atoms. Consequently, the change of refractive index with temperature is proportional to the specific heat capacity. A high-temperature quantum effect is recorded by measuring the temperature-dependent material dispersion of silica glass. The number of the vibration modes per molecule varies stepwise with temperature. Because of the sluggish transition, the microcrystalline structures coexist in the glass. The detected quantum effect is related to the transitions between the “frozen-in” microcrystalline phases in glassy matrix.</div></div>","PeriodicalId":16811,"journal":{"name":"Journal of Physics and Chemistry of Solids","volume":"208 ","pages":"Article 113016"},"PeriodicalIF":4.3,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144655480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the hierarchical samples, CuS, CuS/rGO, CuS/GCN, and CuS/rGO/GCN composites, CuS/rGO demonstrated significantly improved DC and AC conductivity, attributed to the presence of abundant free charge carriers and the conductive 2D framework of rGO. AC conductivity followed Jonscher's universal power law, with the frequency exponent (S) ranging from 0.64 to 0.92. Notably, the CuS/rGO/GCN ternary composite exhibited superior dielectric and charge transport properties, driven by the synergistic interplay among CuS, rGO, and GCN. The dielectric constant (<em>ε</em>′) of the CuS/rGO/GCN composite showed highest value of 2921—approximately tenfold higher than that of pristine CuS (<em>ε</em>′ = 192.9). The dielectric relaxation behaviour was modelled using the Havriliak–Negami model, revealing a non-Debye type relaxation mechanism with absorption coefficient (α) less than 1 (0.58–0.86). The improved dielectric properties are attributed to strong interfacial and space charge polarization effects.
