Rogacheva [et al.] // Materials Today : Proceedings. – Electronic text data. – 2021. – Vol. 44, Pt. 4. – P. 3506-3510. – URL: https://www.sciencedirect.com/science/article/pii/S2214785320368565?via%3Dihub#kg005https://repository.kpi.kharkov.ua/handle/KhPI-Press/61809It was established that the dependences of thermoelectric and mechanical properties of cold-pressed Bi2(Te1−xSex)3 alloys on composition (x = 0–0.07) exhibit a non-monotonic behavior in certain concentration ranges: an anomalous decrease in the Seebeck coefficient, thermoelectric power factor, and microhardness, and increase in electrical conductivity with increasing x. We observed similar anomalies earlier for cast Bi2(Te1−xSex)3 alloys and explained them by percolation and self-organization phenomena. Thus, the existence of the anomalies does not depend on the method of sample preparation. However, in pressed samples as compared to cast ones conductivity type changes from p to n and thermoelectric power factor increases.enBi2(Te1−xSex)3 solid solutionscompositionthermoelectric propertiesmicrohardnesspercolationself-organizationArticledoi.org/10.1016/j.matpr.2020.09.159https://orcid.org/0000-0001-7584-656Xhttps://orcid.org/0000-0002-8116-6189https://orcid.org/0000-0002-9638-7080https://orcid.org/0000-0003-2578-1109
