Fig. 6: Schematic reaction mechanism of the epitaxial growth.
From: Gas-assisted transformation of gold from fcc to the metastable 4H phase
HRTEM image showing the propagation between the fcc crystal lattices of the nanoparticles and 4H phase of the rod region before (a) and after (b) reaction. Both the scale bars in panel a–b corresponds to 5 nm. Please note that the interface between the 4H and fcc phases are labeled by the red dashed lines. c–e The atomic models schematically showing the fcc-to-4H transformation process.
