Accurate measurement of Seebeck coefficient

Review of Scientific Instruments, 2016
In this work, it was investigated how to measure Seebeck coefficient accurately. The offset voltages, between the specimen and measurement wires, might influence the results measured significantly and should be eliminated during measuring process. They do not depend on temperature difference but on temperature and include two parts: the intrinsic ...

Effective Mass from Seebeck Coefficient

Advanced Functional Materials, 2022
AbstractEngineering semiconductor devices requires an understanding of the effective mass of electrons and holes. Effective masses have historically been determined in metals at cryogenic temperatures estimated using measurements of the electronic specific heat.

Seebeck coefficient of K2SO4

Materials Research Bulletin, 1983
Abstract The thermopotential of the cell (SO 2 +O 2 ), Pt/K 2 SO 4 /Pt, (SO 2 +O 2 )′ was measured, and a Seebeck coefficient of 1.6 mV/°C was obtained. This value is higher than that of most salts that have been measured to date. The high Seebeck coefficient has implications in the use of the cell in SO 2 gas measurements.

Seebeck Coefficient (Thermopower)

2007
Based on the idea that different temperatures generate different carrier densities and the resulting carrier diffusion causes the thermal electromotive force (emf), a new formula for the Seebeck coefficient (thermopower) S is obtained: \(S = (2\ln{2} /3)(qn)^{-1}\epsilon_{F}k_{B}({\cal N}_{0}/V)\), where q, n, \(\epsilon_{F}\), \({\cal N}_{0}\), and V ...

High temperature Seebeck coefficient metrology

Journal of Applied Physics, 2010
We present an overview of the challenges and practices of thermoelectric metrology on bulk materials at high temperature (300 to 1300 K). The Seebeck coefficient, when combined with thermal and electrical conductivity, is an essential property measurement for evaluating the potential performance of novel thermoelectric materials. However, there is some

Reference Material for Seebeck Coefficients

International Journal of Thermophysics, 2014
This paper describes a measurement method and a measuring system to determine absolute Seebeck coefficients of thermoelectric bulk materials with the aim of establishing reference materials for Seebeck coefficients. Reference materials with known thermoelectric properties are essential to allow a reliable benchmarking of different thermoelectric ...

Effective Seebeck coefficient for semiconductors

Physical Review B, 2006
A distinction between two common definitions of Seebeck coefficient is clarified. The effective Seebeck coefficient, which describes the effective electric field induced by a temperature gradient, is found to be a constant for a homogeneous doped semiconductor regardless of its doping.
