Diagram of the apparatus.
(a) Structure of the sample test stage; (b) temperature control loop of sample gradient; and (c) temperature control loop of thermostat layer.
The schematic of SC measuring principle. T sample is sample temperature, T hot is hot side temperature, T cold is cold side temperature, ΔT is the difference between cold and hot sides, and V s is the Seebeck voltage with respect to the hot side.
Seebeck voltage signal conditioning circuit diagram.
Temperature variance of thermostat layer (T base ) over 2 h.
Steps of temperature gradient between two sample holders. (Inset) The linear regression line of ΔT and the heated power difference, the correlation coefficient R 2 = 0.999.
