Interaction energy vs interparticle separation for representative NPs: (A) homodimer Pd cube25 nm with Pd cube25 nm; (B) homodimer Au sphere90 nm with Au sphere90 nm; (C) heterodimer Au sphere90 nm with Pd cube25 nm; (D) multimer Pd cube25 nm with different Au sphere90 nm–Pd cube25 nm (ABn) multimers. The legend in (D) describes the composition of the multimers considering one NP A (Au sphere90 nm) and different numbers of NPs B (Pd cube25 nm).
