Method for determining Seebeck coefficient of sample, involves placing two sensors on surface of sample, and measuring representative magnitude of temperature difference between sensors at different times

摘要

The method involves placing two sensors on a surface of a sample (6), where each sensor comprises two electrodes. Succession cycle of temperature gradient is applied between contact points by heat exchange of the sensors between the sample and a thermal unit. Representative magnitude of the temperature difference between the sensors is measured at different times. The Seebeck coefficient of the sample is estimated by the function of a slope interpolated between potential difference of frames and the representative magnitude at the difference temperature and different times. Independent claims are also included for the following: (1) an apparatus for determining Seebeck coefficient of a sample (2) a method for characterization of a material.
