Extended Data Fig. 9: Results from Ir-coated quartz gold nanoparticle (AuNP) experiment.
From: Gold nugget formation from earthquake-induced piezoelectricity in quartz
Imagery of the Ir-coated quartz crystal slab after deformation within AuNP solution. (a) BSE image of the quartz surface exhibiting distribution of gold particles deposits from AuNP solution. Large clusters of AuNPs can be seen. (b) and (c) are BSE and SE images, respectively, of the square area outlined in (a). (d) EDS image of the square area in (a) highlighting the chemistry of sample area. BSE: Backscattered electron. SE: Secondary electron. EDS: Energy dispersive spectroscopy.
