Thermal conductivity comparison method based on silicon diode thermometry.
A room-temperature thermal conductivity comparison method is described which does not required calibrated thermometers and which involves temperature rises <1 K. The method is based on silicon diode thermometry, and the results obtained on three unknowns measured against alumina are presented. For the short samples measured, the uncertainty is approximately +/-5%. Methods for applying the technique at other temperatures and for improving the accuracy are discussed.
