Fig. 5From: High Seebeck Coefficient of Porous Silicon: Study of the Porosity DependenceExample of experimental data for the 46 % porosity sample. In a, the thermovoltage and the temperature difference versus time are depicted for the 46 % porosity sample. In b, the ΔV versus ΔT curve is plotted, from which S is determined by a linear fit to the dataBack to article page
