Fig. 4 — The effect of electromagnetic hot spots on the phase transformation reaction. a Calculated field enhancement for the antenna (Au) – reactor (Pd) system under planewave excitation at 690 nm. The corners of the Pd nanocube are labeled 1-4 with 1 being the corner closest to the hot spot and 4 the farthest. Scale bar is 50 nm. b Distribution of plasmon-induced phase transformation events by corner number. c Distribution of plasmon-induced phase transformation events with respect to the distance between the nanodisc (antenna) and the nanocube (reactor). Negative antenna-reactor distance values correspond to a physical overlap between the nanodisc and the nanocube. The size of the markers corresponds to a single unloading event (small markers), 2 unloading events (medium markers) and 3 unloading events (big markers). Edge events are marked with bars spanning the two corners comprising the edge. For the summary analysis of b, we assign each edge unloading event to one corner number (the lower corner number)
