Abstract
En 中文
Substrate dielectric screening profoundly modifies the intrinsic electronic states of adsorbed molecules. Here, we demonstrate continuous tuning of electronic screening for a single C60 molecule by manipulating it onto ultrathin NaCl films on Ag(111). STS measurements reveal a striking orbital-dependent asymmetry: the HOMO shifts to higher binding energy with increasing NaCl thickness, while the LUMO remains pinned. This asymmetry response arises from an interface state at the NaCl/Ag boundary that selectively pins the LUMO, while the HOMO responds to reduced screening. Our findings establish that electronic screening at molecule-metal interfaces is inherently orbital-specific, providing critical insight for molecular-scale device design.
