Thermoelectric energy conversion efficiency is defined as ZT = S2 σ /χT, where S is the Seebeck coefficient, = is the electrical conductivity, χ is the thermal conductivity, and T is the absolute temperature.  This study is aimed at increasing the thermoelectric figure of merit ZT to maximize the power factor and minimize the thermal conductivity.  Since undoped Bi–12at%Sb alloys are of n-type, the possibility of obtaining p-type Bi–Sb alloys (bulk samples and layers) with a high figure of merit by the addition of acceptor impurities and the application of a transverse magnetic field has been explored.  The mechanical exfoliation method was used to obtain Bi1-xSbx layers and the liquid-phase casting method (Ulitovsky–Tailor) was used to prepare wires [1].  In this paper, we present the results of measurements of transport effects in undoped and doped Bi–12at%Sb–0.001at%Pb alloy bulk samples, single-crystal layers, and glass-insulated wires. The measurements included the electrical resistivity, Seebeck coefficient S, and the Nernst coefficient as a function of crystallographic direction, temperature, and magnetic field direction.  The values and temperature dependence of power factor α2 σ, which were calculated from experimental data in a transverse magnetic field, showed a considerable increase in this parameter in the wires and layers compared with the bulk samples in a magnetic field of 0.3 T [2, 3]. A combination of the Peltier and magneto-Peltier effects in Bi–Sb layers and wires provides a stronger cooling both from room temperature and from 100 K than the cooling in bulk alloys of the same composition.

<dc:description xml:lang='en'>This article broaches the specifics of George Topârceanu’s poetry, and relying on the remarks of some Romanian literary exegetes, we conclude that this is the poem of „minor universe”, with pronounced neoclassical accents. One of the ways to realize this poem is the symbiosis between the native vocabulary and the academic one. </dc:description>
