TEM images of the morphology evolution of thin Au coatings on iron oxide
substrates for continuous addition of precursor as a function of the total
Au3+/Fe mass ratio. A-C are low res TEM images while D-F are high
resolution TEM images with different Au3+/Fe. A,
Au3+/Fe = 0.125. B, Au3+/Fe = 0. 25.
C, Au3+/Fe = 0.5. D, Au3+/Fe
= 0.125. E, Au3+/Fe = 0. 25. F,
Au3+/Fe = 0.5.
