Periodic application of the sequence ‘growth and ion-induced stress relaxation’: A way to prepare stable, thick films of cubic boron nitride
TL;DR: A short review of the current status of preparing films of cubic Boron Nitride, a material exhibiting similar attractive properties as diamond, can be found in this paper, where a procedure allowing to obtain thick (>1μm), stress relieved, superhard (48 GPa) samples, which are mechanically stable under ambient conditions.
Journal ArticleDOI
Evidence for phase separation of ethanol-water mixtures at the hydrogen terminated nanocrystalline diamond surface
Stoffel D. Janssens,Sien Drijkoningen,Marc Saitner,Hans-Gerd Boyen,Patrick Wagner,Karin Larsson,Ken Haenen +6 more
TL;DR: The model suggests that, due to a higher affinity of ethanol for the hydrophobic surface, when compared to water, a phase separation occurs when a mixture of both liquids is in contact with the H-terminated diamond surface.
Journal ArticleDOI
Electrocatalytic Behavior of Pd and Pt Nanoislands Deposited onto 4,4′-Dithiodipyridine SAMs on Au(111)
Heiko Müller,Martin Metzler,Natalie Barth,Bert Conings,Hans-Gerd Boyen,Timo Jacob,Ludwig A. Kibler +6 more
TL;DR: Using different electrochemical techniques as well as in situ scanning tunneling microscopy (STM) and ultraviolet photoelectron spectroscopy (UPS), this article investigated the electrocatalytic oxidation of carbon monoxide and methanol on palladium and on platinum nanoislands, which were deposited onto 4,4′-dithiodipyridine self-assembled monolayers (SAMs) on Au(111) single crystal electrodes.
Journal ArticleDOI
Electronic structure of liquid tungsten studied by time-resolved photoelectron spectroscopy
TL;DR: In this article, the electronic structure of liquid tungsten has been studied by time-resolved photo electron spectroscopy on laser pulse molten surface layers and the valence band spectra reveal distinct changes of the electronic structures across the solid-liquid phase transition.
Journal ArticleDOI
Resistivity and phonon softening in ion-irradiated epitaxial gold films
TL;DR: In this article, the influence of ion irradiation-induced defects on the temperature dependence of the resistivity of epitaxial, thin (25nm), and ultrathin (7nm) gold films was investigated.
