Fig. 4From: High Seebeck Coefficient of Porous Silicon: Study of the Porosity DependenceDiagnostic test measurement for hysteretic behaviour. Thermovoltage versus temperature difference for two heating rates, namely 20 mK/s (red open squares) and 0.8 mK/s (black dots). The two curves coincide, which is an indicator of good thermal contacts and the absence of hysteresis effectBack to article page
