Temperature and magnetic field dependences of thermoelectric properties of Bi1-xSbx solid solutions in the range x = 0-0.25 [Electronic resource] / E. I. Rogacheva, A. N. Doroshenko, O. N. Nashchekina // Materials Today : Proceedings. – Electronic text data. – 2021. – Vol. 44, Pt. 4. – P. 3458-3462. – URL: https://www.sciencedirect.com/science/article/pii/S2214785320319945?via%3Dihubhttps://repository.kpi.kharkov.ua/handle/KhPI-Press/61806Bi1–xSbx solid solutions are the best n-type thermoelectric materials for use at temperatures ≤200 K. An important parameter determining material’s figure of merit is charge carrier concentration. To determine it correctly, one should carry out measurements in a weak magnetic field. On the basis of the magnetic field dependences of the Hall coefficient and magnetoresistance, the dependences of the weak magnetic field boundary Bc on composition (x = 0–0.25) and temperature (T = 77–300 K) for polycrystalline Bi1–xSbx alloys were plotted. It was established that the Bc(x) dependences exhibit a non-monotonic behavior which is attributed to the existence of electronic phase transitions.enBi1–xSbx solid solutionscompositionmagnetic fieldtemperatureHall coefficientmagnetoresistanceArticledoi.org/10.1016/j.matpr.2020.03.214https://orcid.org/0000-0001-7584-656Xhttps://orcid.org/0000-0002-9638-7080https://orcid.org/0000-0003-2578-1109
