  • In superconducting thin films of a few atomic layers, surface and bulk orders may compete. Here, the authors measure how the Pearl length, which characterizes the distribution of magnetic field in vortices, varies with thickness in NbSe2, showing that surface superconductivity dominates at low thickness.

  • Here, the authors develop a spectroscopic technique whereby individual defects in an ultrathin hBN dielectric, placed in proximity to graphene, act as quantum dots. Dot-assisted tunneling is highly sensitive to the nearby graphene excitation spectrum, and allows probing of energy splitting in the excited Landau levels.
