FIG. 1.

(Color online) (a) Schematic description of the experiment. (b) Heat exchange diagram for modeling the system. The sample and the sample-holder are connected with a thermal link . At the same time, both parts are connected with a thermal bath at a constant temperature T0 through the thermal links and for the sample and the sample-holder, respectively.

FIG. 2.

(Color online) Temperature difference as a function of time for different applied voltages. The voltage is applied during 600 s and then it is turned off. The lines are the fitting function using Eq. (3).

Image of FIG. 3.
FIG. 3.

(Color online) Fitting parameters obtained from the measurements shown in Fig. 2 at different applied voltages. Characteristic times (panel a), A 1 (panel b), and (panel c). The Joule heating contribution is presented as a dotted line in panel (c). Circles and triangles indicate increasing and decreasing voltage, respectively.
