  • Mica is a naturally occurring 2D mineral that has been heavily studied in many diverse areas. Here authors present atomic force microscopy images to study the mica surface in ultra-high vacuum conditions; they unveil the distribution of its surface K+ ions and give insights into the distribution of subsurface Al3+ ions.

  • Non-contact atomic force microscopy measurements are used to probe the hydrogen bond strength of individual surface hydroxyl groups and determine their acidity with atomic precision.

  • Defect-free surfaces with excess charge are typically described as a homogeneous 2D electron gas. Here, in contrast, the authors find that the KTaO3(001) surface hosts a charge density wave coexisting with a pattern of electron polarons, highly localized states of excess electrons bound to a lattice distortion.

  • Surface structures can have an important effect on the traits of two-dimensional electron liquids. Here, the authors demonstrate how the surface terminations of SrTiO3(001) affect the mechanism and properties of the two-dimensional electron liquid.

  • Polarons — quasiparticles arising from the interaction of electrons with lattice vibrations — strongly influence materials properties. This Review provides a map of the theoretical models and experimental techniques used to study polarons in materials, presenting paradigmatic examples of different types of polarons and polaron-driven phenomena.
