Boron-Doped Strontium-Stabilized Bismuth Cobalt Oxide Thermoelectric Nanocrystalline Ceramic Powders Synthesized via Electrospinning

Different concentrations of Ti4+ as a donor and electronic properties of Bi2-xTixO3

“…Frontiers in Materials frontiersin.org 03 of all doped samples has an almost similar trend till 300 °C, however, the Seebeck coefficient of pure ceramic (BO) has shown a slight decrease after 200 °C as compared to other doped samples. The samples show enhancement in electrical conductivity and the Seebeck Coefficient after Ti doping which could lead to high power factor values as compared to the un-doped sample (Koçyiğit et al, 2014;Koçyiğit et al, 2019;Ghosh et al, 2020). Among all compositions, as-prepared samples BO-0.03T has the highest Seebeck value, i.e., 47 μV/ °C which shows the presence of a higher carrier concentration (Terasaki, 2011), while BO-0.03T has the second-highest electrical conductivity value.…”

Variations of the Thermoelectric Characteristics of ZnO Nanofibers from the Use of a Thermal Treatment

“…In relation to the conventional thermoelectric nanomaterials, the advantages of the oxide NFs are derived from sufficient length dimensions that enable real-life oxide-NF applications [5][6][7]. Most NFs have been prepared with electrospinning and a subsequent thermal treatment, the latter of which affects the NF diameter and the residual-polymer quantity.…”

“…In terms of the fabrication of thermoelectric modules that are composed of n-type and p-type NF couples, n-type oxide NFs are important; however, a paucity of studies regarding the n-type oxide NFs presently exists, while the p-type oxide NFs including ptype Ca 3 Co 4 O 9 and p-type LaSrCoO 3 have been widely researched [6][7][8][9][10]. In this study, n-type ZnO thermoelectric NFs are therefore prepared, and the heating-time-based variations of the thermoelectric characteristics of these ZnO NFs are examined.…”
