Figure 4
Nanocalorimetric signal (symbols) for samples formed by 75 nm a-Si and 60 nm Pd bilayers at three different heating rates: (a) 0.1, (b) 1 and (c) 10 K s−1. The background of each graph corresponds to a two-dimensional plot of the XRD patterns. Colour variation within each graph indicates the relative intensity of the XRD peaks. Dashed vertical lines mark the onset of Pd consumption (grey) and the appearance of the Pd2Si diffraction peak (dark grey) obtained from the analysis of the XRD spectra. |
