The transparency of two-dimensional (2D) materials to intermolecular interactions of
crystalline materials has been an unresolved topic. Here we report that remote atomic
interaction through 2D materials is governed by the binding nature, that is, the polarity of
atomic bonds, both in the underlying substrates and in 2D material interlayers. Although the
potential field from covalent-bonded materials is screened by a monolayer of graphene, that
from ionic-bonded materials is strong enough to penetrate through a few layers of graphene …

This thesis reports a systematic understanding of remote atomic interaction through two-
dimensional (2D) materials, unveiling the general rules for atomic potential" transparency"
that can be universally applied to any 2D material. Our findings indicate that:(1) the degree
of ionicity of 3D materials determines the potential field penetration depth, and (2) the
iconicity of 2D material interlayer governs the degree of screening of the field from the 3D
materials. Thus, pure ionically-bonded materials can substantially transmit their potential …
