Germanium (Ge)-based thermoelectric materials have proven to be a reliable and sustainable solution for efficient energy harvesting across a wide range of temperatures for an extended period. Numerous investigations have been published addressing the future scope of Ge as a thermoelectric material. This article offers a comprehensive bibliometric analysis of the literature related to Germanium-based thermoelectric energy harvesting (Ge-TEH) materials available on Scopus to identify how this material contributes to thermoelectric energy generation. Methodologies such as citation analysis, co-authorship, and co-occurrence analysis are employed to analyze refined data of „1867‟ documents using VOS viewer and Biblioshiny. The analysis shows that Ge-TEH has grown significantly worldwide, especially in the last decade. The social and intellectual networks were generated, and the most influencing countries, sources, and institutions were identified. China and the United States (USA) were found to have the highest number of publications, citations, and collaborations. The keywords analysis reveals that „lattice thermal conductivity,' „Germanium,' „Seebeck coefficient,' „spark plasma sintering', and 'density functional theory‟ are the most occurring words, indicating that the dataset features keywords related to thermoelectric materials and their properties. It also suggests a strong emphasis on fabrication methods for optimizing thermoelectric properties. The mutual relevance and categorical patterns of frequently occurring keywords were studied using a factorial analysis graph. This detailed analysis provides critical findings into the evolution and future scope of the research in Ge-TEH.

In the present work, flower-like Cu2SrSnS4 (CSTS) sample is successfully prepared by solvothermal method. The XRD and Raman analysis confirm that pure CSTS phase with trigonal structure is obtained. The band gap of as-obtained CSTS naocrystals is estimated to be 1.49eV. The removal of methylene blue (MB) within 100min under simulated solar light irradiation is around 90%, depicting that CSTS is a potential material for effective solar light photocatalytic application. Meanwhile, The Seebeck coefficient and electrical conductivity of CSTS material can reach to 128.57μV•K-1 and 20.35S·m-1 at 675K, respectively, indicating its potential for thermoelectric application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
