Extended Data Fig. 5: Secondary knock-on-induced demetallation of complexed Pb atoms through a fast atom flux.
a, Schematic depiction of energy transfer ET from primary electrons to atoms (H, C, N, Pb) and subsequent energy transfer ET’ from the fast moving atoms to Pb atoms, calculated from Eq. 1 and 2. b, Maximum transferred kinetic energy from the primary beam via elastic scattering against the kinetic energy of the primary electrons. c, Maximum transferred kinetic energy from fast atoms to Pb atoms via secondary knock-on energy transfer against the kinetic energy of the primary electrons.
