Extended Data Fig. 3: Transmission of the partially cut versions of Si222.

a, Chemical structures of Si222-1bridge and Si222-2bridge. b, Transmission data of Si222 in anti-conformation with different number of bridges being cut. c–e, Transmission pathways are shown for (c) Si222-1bridge (one bridge remains, two were cut), (d) Si222-2bridge (two bridges remain, one was cut) and (e) Si222. The transmission of the Si222-2bridge junction is almost as high as Si222-cut junction where all three bridges are cut, because the bridge where the interference signature appears is cut (d). If we instead cut the other two bridges simultaneously (c, Si222-1bridge), the ring current pathways and the antiresonance in the transmission persist.
