Coordination-resolved local bond strain and 3p energy entrapment of K atomic clusters and K(1Â 1Â 0) skin

- Coordination environment resolves electron binding-energy shift of K44, K46, K55 clusters.
- Predict the effective coordination number of K nanoclusters when we get the atomic number N.
- Atomic under coordination shortens the local bonds and entrapment.
- XPS derives core level of an isolated atom and its bulk shift.
