Query: Reflections on the spatial performance of atom probe tomography in the
  analysis of atomic neighbourhoods   Atom probe tomography is often introduced as providing "atomic-scale" mapping
of the composition of materials and as such is often exploited to analyse
atomic neighbourhoods within a material. Yet quantifying the actual spatial
performance of the technique in a general case remains challenging, as they
depend on the material system being investigated as well as on the specimen's
geometry. Here, by using comparisons with field-ion microscopy experiments and
field-ion imaging and field evaporation simulations, we provide the basis for a
critical reflection on the spatial performance of atom probe tomography in the
analysis of pure metals, low alloyed systems and concentrated solid solutions
(i.e. akin to high-entropy alloys). The spatial resolution imposes strong
limitations on the possible interpretation of measured atomic neighbourhoods,
and directional neighbourhood analyses restricted to the depth are expected to
be more robust. We hope this work gets the community to reflect on its
practices, in the same way, it got us to reflect on our work.
