Local density of states and interface effects in semimetallic ErAs nanoparticles embedded in GaAs.

Physical review letters

Kawasaki JK, Timm R, Delaney KT, Lundgren E, Mikkelsen A, Palmstrøm CJ.
PMID: 21838391
Phys Rev Lett. 2011 Jul 15;107(3):036806. doi: 10.1103/PhysRevLett.107.036806. Epub 2011 Jul 14.

The atomic and electronic structures of ErAs nanoparticles embedded within a GaAs matrix are examined via cross-sectional scanning tunneling microscopy and spectroscopy (XSTM/XSTS). The local density of states (LDOS) exhibits a finite minimum at the Fermi level demonstrating that...

A very rich Fe-C phase diagram makes the formation of graphene on iron surfaces a challenging task. Here we demonstrate that the growth of graphene on epitaxial iron films can be realized by chemical vapor deposition at relatively low...

The Corpus Callosum Wallerian Degeneration in the Unilateral Brain Tumors: Evaluation with Diffusion Tensor Imaging (DTI).

Spatial Control of Multiphoton Electron Excitations in InAs Nanowires by Varying Crystal Phase and Light Polarization.

Nano letters

Mårsell E, Boström E, Harth A, Losquin A, Guo C, Cheng YC, Lorek E, Lehmann S, Nylund G, Stankovski M, Arnold CL, Miranda M, Dick KA, Mauritsson J, Verdozzi C, L'Huillier A, Mikkelsen A.

Nano Lett. 2018 Feb 14;18(2):907-915. doi: 10.1021/acs.nanolett.7b04267. Epub 2018 Jan 11.

We demonstrate the control of multiphoton electron excitations in InAs nanowires (NWs) by altering the crystal structure and the light polarization. Using few-cycle, near-infrared laser pulses from an optical parametric chirped-pulse amplification system, we induce multiphoton electron excitations in...

Self-cleaning and surface chemical reactions during hafnium dioxide atomic layer deposition on indium arsenide.

Nature communications

Timm R, Head AR, Yngman S, Knutsson JV, Hjort M, McKibbin SR, Troian A, Persson O, Urpelainen S, Knudsen J, Schnadt J, Mikkelsen A.

Nat Commun. 2018 Apr 12;9(1):1412. doi: 10.1038/s41467-018-03855-z.

Atomic layer deposition (ALD) enables the ultrathin high-quality oxide layers that are central to all modern metal-oxide-semiconductor circuits. Crucial to achieving superior device performance are the chemical reactions during the first deposition cycle, which could ultimately result in atomic-scale...

Heusler compounds are a ripe platform for discovery and manipulation of emergent properties in topological and magnetic heterostructures. In these applications, the surfaces and interfaces are critical to performance; however, little is known about the atomic-scale structure of Heusler...

Arabinoxylan (AX) and xyloglucan (XG) are important components of primary cell walls of cereal grains and vegetables/fruits, respectively. Despite the established health benefits of these non-starch polysaccharides, the mechanisms of their utilisation by the gut microbiota are poorly understood....
