Quantum size effect (QSE) has been studied extensively, as a primary driving force for nano technology. By first-principles calculations of ultrathin Pb(111) films, we show that the QSE is not merely a size effect but also symmetry driven. For this reason, quantum symmetry could be essential for near-field physics and especially important for surface reactivity, in particular, in the study of molecular adsorption, reactivity and catalysis to refine the current reactivity theory.
