nm-Range forces acting between calcite surfaces in water affect macroscopic properties of carbonate rocks and calcite-based granular materials and are significantly influenced by calcite surface recrystallization. We suggest ...
The α and γ plasma modes in plasma-enhanced atomic layer deposition with O2-N2 capacitive discharges
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
Two distinguishable plasma modes in the O2–N2 radio frequency capacitively coupled plasma (CCP) used in remote plasma-enhanced atomic layer deposition (PEALD) were observed. Optical emission spectroscopy and spectra ...
