Tailoring the Electronic Structure of Ni(111) by Alloying with Sb Ad-Atoms
Anna Cecilie Åsland, Alv Johan Skarpeid, Matthias Hartl +8
Surface alloying can alter surface electronic and magnetic properties, which are key parameters when developing new materials tailored for specific applications. A magnetic surface…
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…
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…
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,…
The Diamond (111) Surface Reconstruction and Epitaxial Graphene Interface
B. P. Reed, M. E. Bathen, J. W. R. Ash +6
The evolution of the diamond (111) surface as it undergoes reconstruction and subsequent graphene formation is investigated with angle-resolved photoemission spectroscopy, low ener…
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…
Observation and origin of the -manifold in Si:P -layers
Ann Julie Holt, Sanjoy K. Mahatha, Raluca-Maria Stan +9
By creating a sharp and dense dopant profile of phosphorus atoms buried within a silicon host, a two-dimensional electron gas is formed within the dopant region. Quantum confinemen…
The occupied electronic structure of ultrathin boron doped diamond
A. K. Schenk, A. C. Pakpour-Tabrizi, A. J. U. Holt +9
Using angle-resolved photoelectron spectroscopy, we compare the electronic band structure of an ultrathin (1.8 nm) δ-layer of boron-doped diamond with a bulk-like boron doped diamo…
Ubiquitous formation of bulk Dirac cones and topological surface states from a single orbital manifold in transition-metal dichalcogenides
M. S. Bahramy, O. J. Clark, B. -J. Yang +23
Transition-metal dichalcogenides (TMDs) are renowned for their rich and varied properties. They range from metals and superconductors to strongly spin-orbit-coupled semiconductors…
Silver catalyzed Fluorouracil degradation; a promising new role for graphene
Federico Mazzola, Thuat Trinh, Simon Cooil +9
Chemotherapy treatment usually involves the delivery of fluorouracil (5-Fu) together with other drugs through central venous catheters. Catheters and their connectors are increasin…
