a Representative STM image of Au4Pt2(SR)8 on a HOPG substrate. b STS profile of single Au4Pt2(SR)8 cluster on graphite surface. c Calculated frontier orbitals of single Au4Pt2(SR)8 cluster. d Representative AFM image of Au4Pt2(SR)8/G. e STEM-ADF image of Au4Pt2(SR)8 deposited on defective graphene. f High-resolution STEM-ADF images of single Au4Pt2(SR)8 clusters and approximate corresponding orientations(scale bars in Fig. 2f are 5 Å). Colors: golden, Au; white, Pt; yellow, S; gray, C. Sulfur, carbon, and hydrogen atoms are omitted for clarity in (f).
