Surfaces, interfaces and thin films

Surfaces, interfaces and thin films are planar structures that occur on the boundary of a material or at the junction between two different media. The physics of these systems is often heavily influenced by their two-dimensional nature.

    Using electric field gating, researchers demonstrate switching from a single- to a multi-condensate superconducting state at an oxide-based interface, and show that this transition leads to an overall weakening of the superconductivity.

    Water–surface interactions are strongly influenced by the polar or non-polar nature of the chemical groups on the surface. Jacob Monroe and Scott Shell used molecular dynamics simulations and genetic algorithms to show that the specific patterns of such functionalities effect water dynamics.

    Design principles for the development of silicon biointerfaces enable the non-genetic, light-controlled modulation of intracellular Ca2+ dynamics, and of cellular excitability in vitro, in tissue slices and in mouse brains.
