Abstract

Apparatus for measuring the Seebeck coefficients of highly resistive organic semiconducting materials Rev. Sci. Instrum. 84, 044703 (2013); 10.1063/1.4799968 Apparatus for measuring Seebeck coefficients of highresistance semiconducting films Rev. Sci. Instrum. 55, 754 (1984); 10.1063/1.1137812 Conduction models of semiconducting calcium borate glasses containing iron oxideThe Seebeck coefficient, el, of semiconducting glasses based on vanadium pentoxide can be calculated from a knowledge of the concentration ratio of the high and low valence ions. The concentration of vanadium ions in the glass and long-range order apparently have no effect on el. Semiconducting glasses based on iron oxide, however, are not amenable to the simple treatment presently developed.The effect of nuclear magnetic double resonance on an AB+C system, in which A is in chemical exchange with C, is discussed. A strong irradiation at C causes the spin states of A to saturate, while the splitting of B by A is not influenced. When the chemical shift between A and B (V05AB) is comparable to their coupling constant ( JAB) , the indirect spin saturation of A may in turn cause B to saturate via spin-spin interaction. An expression for the ratio of intensity of the AB system after and before irradiating C is obtained in terms of V05AB, JAB, and factors accounting for the rate of exchange and relaxation time.

Electric conductivity of glasses in the system Na2O/CaO/SiO2/Fe2O3

“…Eq. (1) was used in order to evaluate the specific conductivity [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

“…The conductivity of phosphate, borate, vanadate and tellurite glasses and also of ternary silicate glasses containing transition metal ions has frequently been reported in the literature [10,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Besides, the conductivity of glasses and glassy materials from the system PbO/SiO 2 / Fe 2 O 3 was studied [15].…”

Majority charge carrier reversal and its effect on thermal and electron transport in xV2O5–(1−x) As2O3 glasses

“…According to Allersma et al [52], the Seebeck coefficient, S, can be expressed, from the theory of irreversible thermodynamics, in terms of the chemical potential, μ, and the "transport heat" per particle, Q ⁎ [53],…”

Co-Sb- and Zn-Sb-Based Thin-Film Thermoelectric Modules for Temperature Sensors

“…This makes a TEG a good candidate for a temperature sensor because it has a largely different value in Nand P-type legs; they have different signs owing to different charge carriers. (7) Moreover, the possibility of powering such a sensor system with a thermoelectric voltage obtained from a temperature gradient without any external power sources makes this application environmentally friendly.…”
