Low temperature atomic layer deposition of cobalt using dicobalt hexacarbonyl-1-heptyne as precursor

Beilstein Journal of Nanotechnology, 2023
In this work, we present the development of an atomic layer deposition (ALD) process for metallic cobalt. The process operates at low temperatures using dicobalt hexacarbonyl-1-heptyne [Co2(CO)6HC≡CC5H11] and hydrogen plasma.

Practical guide to the use of backgrounds in quantitative XPS

Journal of Vacuum Science and Technology, 2021
This guide is intended for both the novice in x-ray photoelectron spectroscopy (XPS) as well as users with some experience. XPS is one of the most widely used methods to characterize surface nanostructured samples, and XPS is now also commonly accessible

Search for an Near-IR Counterpart to the Cas A X-ray Point Source [PDF]

, 2001
We report deep near-infrared and optical observations of the X-ray point source in the Cassiopeia A supernova remnant, CXO J232327.9+584842. We have identified a J=21.4 +/- 0.3 mag and Ks=20.5 +/- 0.3 mag source within the 1-sigma error circle, but we ...

Demonstration of chemistry at a point through restructuring and catalytic activation at anchored nanoparticles

Nature Communications, 2017
Metal nanoparticles prepared by exsolution at the surface of perovskite oxides are key species in catalysis and energy fields. Here, the authors develop a chemistry at a point concept by tracking individual nanoparticles with excellent activity and ...

Practical guides for x-ray photoelectron spectroscopy: Quantitative XPS

Journal of Vacuum Science and Technology, 2020
X-ray photoelectron spectroscopy (XPS) is widely used to identify chemical species at a surface through the observation of peak positions and peak shapes. It is less widely recognized that intensities in XPS spectra can also be used to obtain information

Electron Conditioning of Technical Aluminium Surfaces: Effect on the Secondary Electron Yield [PDF]

, 2004
The effect of electron conditioning on commercially aluminium alloys 1100 and 6063 were investigated. Contrary to the assumption that electron conditioning, if performed long enough, can reduce and stabilize the SEY to low values ($\leq 1.3$, value of ...

Analysis of Wear Track on DLC Coatings after Sliding with MoDTC-Containing Lubricants

Tribology Online, 2017
Wear of DLC coating has been great concern in DLC/Steel sliding surface lubricated by molybdenum dithiocarbamate (MoDTC) containing lubricants. However, in order to design lubrication system with DLC and MoDTC, the mechanism of this issue is needed to be
