(1) Schematic drawing
of the sequence of steps by which an STM probe can (a) dissociate a
C6H5I molecule on a terrace; (b and c) draw iodine atom away; (d) pull
one C6H5 (phenyl) molecule toward another; (e) weld them together; (f)
pull one phenyl to confirm the association
STM figures showing the above steps.
