Direct measurement of 2DEG states in shallow Si:Sb -layers

Frode S. Strand, Simon P. Cooil, Quinn T. Campbell +13

We investigate the electronic structure of high-density layers of Sb dopants in a silicon host, so-called Si:Sb -layers. We show that, in spite of the known challenges in produc…

Initial Stages of Water Absorption on Surfaces at Very Low Temperatures for Understanding Anti-Icing Coatings

Anna Cecilie Åsland, Simon P. Cooil, Damir Mamedov +5

Anti-icing coatings are intended to prevent ice formation on surfaces, minimising the risk of surface-related damage and also reducing ice-related hazards in society. $\mathrm{CeO}…

Phonon-Mediated Quasiparticle Lifetime Renormalizations in Few-Layer Hexagonal Boron Nitride

Håkon I. Røst, Simon P. Cooil, Anna Cecilie Åsland +9

Understanding the collective behavior of the quasiparticles in solid-state systems underpins the field of non-volatile electronics, including the opportunity to control many-body e…

Probing the Atomic Arrangement of Sub-Surface Dopants in a Silicon Quantum Device Platform

Håkon I. Røst, Ezequiel Tosi, Frode S. Strand +4

High-density structures of sub-surface phosphorus dopants in silicon continue to garner interest as a silicon-based quantum computer platform, however, a much-needed confirmation o…

Disentangling Electron-Boson Interactions on the Surface of a Familiar Ferromagnet

Håkon I. Røst, Federico Mazzola, Johannes Bakkelund +5

We report energy renormalizations from electron-phonon and electron-magnon interactions in spin minority surface resonances on Ni(111). The different interactions are identified, d…

One-Dimensional Spin-Polarised Surface States -- A Comparison of Bi(112) with Other Vicinal Bismuth Surfaces

Anna Cecilie Åsland, Johannes Bakkelund, Even Thingstad +8

Vicinal surfaces of bismuth are unique test-beds for investigating one-dimensional (1D) spin-polarised surface states that may one day be used in spintronic devices. In this work,…

Electron-magnon coupling and quasiparticle lifetimes on the surface of a topological insulator

Kristian Mæland, Håkon I. Røst, Justin W. Wells +1

The fermionic self-energy on the surface of a topological insulator proximity coupled to ferro- and antiferromagnetic insulators is studied. An enhanced electron-magnon coupling is…

Low Temperature Growth of Graphene on Semiconductor

Håkon I. Røst, Rajesh K. Chellappan, Frode S. Strand +13

The industrial realization of graphene has so far been limited by challenges related to the quality, reproducibility, and high process temperatures required to manufacture graphene…
