Here, we reported the observation and characterization of a two-dimensional (2D) ice structure on the highly hydrophobic Au(111) surface using a qPlus-based noncontact atomic force microscope (NC-AFM) with a CO-terminated tip. Our work revealed a peculiar buckled bilayer ice structure with disordered proton distribution, which is modulated by the underlying inhomogeneous surface potential. Those results are further substantiated by density functional theory (DFT) calculations. This work open up the possibility of probing ice growth on hydrophobic surfaces with atomic precision.
