Figure 8
Volumetric thermal expansion coefficient of gold as a function of temperature. The open data points were obtained by numerical differentiation of the data reported in Table S1 and Fig. 2 [equation (11)], selecting a 20 K window (see text). The red solid line represents the calculated real crystal model [equation (10)] and the dashed black line is the perfect crystal component thereof [i.e. Vp(T), see text for details]. Measured values reported in the literature (filled symbols) are also plotted for comparison. |
