Through a combination of experimental techniques we show that the topmost layer of the topological insulator TlBiSe _2 as prepared by cleavage is formed by irregularly shaped Tl islands at cryogenic temperatures and by mobile Tl atoms at room tempera

Lower-dimensional superconductors are typically synthesized on insulating substrates. Here, the authors find that the hybrid electronic structure formed at the interface between a lead film and a semiconducting black phosphorus substrate significantl

Atomic-scale spin order is commonly studied using spin polarized scanning tunneling microscopy. Here, the authors report on a combination of current and exchange force detection together with first-principles calculations demonstrating increased reso

Weak hybridization of two-dimensional metallic materials with their substrates plays a crucial role in charge transfer and doping characteristics. Here, the authors report heavy doping of monolayer 1H-TaS2 synthesized on Au(111) by ab-initio calculat

Single-atom storage can dramatically exceed the limit of traditional high-density memory devices but is challenging. Here the authors show the bistability in the orbital configuration of a single Co atom on black phosphorus which can be accessed, man

Scanning tunnelling microscopes can be used to accurately position atoms and measure emergent behaviour arising from interatomic couplings. Here, the authors fabricate a model spin chain and show the formation of a tunable spiral state due to competi

Artificial lattices derived from assembled atoms on a surface using scanning tunneling microscopy present a platform to create matter with tailored electronic, magnetic, and topological properties. However, artificial lattice studies to date have foc

BCS theory has been widely successful at describing elemental bulk superconductors. Yet, as the length scales of such superconductors approach the atomic limit, dimensionality as well as the environment of the superconductor can lead to drastically d

Bistable valency in individual atoms presents a new approach toward single-atom memory, as well as a building block to create tunable and stochastic multi-well energy landscapes. Yet, this concept of orbital memory has thus far only been observed for

Orbital memory is defined by two stable valencies that can be electrically switched and read out. To explore the influence of an electric field on orbital memory, we studied the distance-dependent influence of an atomic Cu donor on the state favorabi
