abstract = {Ionic liquids have become of significant relevance in
chemistry, as they can serve as environmentally-friendly
solvents, electrolytes, and lubricants with bespoke
properties. In particular for electrochemical applications,
an understanding of the interface structure between the
ionic liquid and an electrified interface is needed to model
and optimize the reactions taking place on the solid
surface. As with ionic liquids, the interplay between
electrostatic forces and steric effects leads to an
intrinsic heterogeneity, as the structure of the ionic
liquid above an electrified interface cannot be described by
the classical electrical double layer model. Instead, a
layered solvation layer is present with a structure that
depends on the material combination of the ionic liquid and
substrate. In order to experimentally monitor this
structure, atomic force spectroscopy (AFS) has become the
method of choice. By measuring the force acting on a sharp
microfabricated tip while approaching the surface in an
ionic liquid, it has become possible to map the solvation
layers with sub-nanometer resolution. In this review, we
provide an overview of the AFS studies on ionic liquids
published in recent years that illustrate how the interface
is formed and how it can be modified by applying electrical
potential or by adding impurities and solvents},
