Identification of chemical species using artificial intelligence to interpret optical emission spectra
… the predictive capabilities of ANN’s is that of optical emission spectra (OES). OES is an important diagnostic for monitoring plasma species within plasma processing. Normally, OES spectral interpretation requires significant prior expertise from a spectroscopist. One way of alleviating this …

Outer-core emission spectroscopy of the heavy alkaline-earth metals
Optical emission spectra from the np$\sp5$ initial core-excited configurations of the alkaline-earth metals calcium, strontium, and barium are presented. The spectra are found to be anomalously broad and red-shifted with regard to XPS core positions. With the help of data from complementary …

Dissociation of carbon dioxide in an Al/Al2O3 microchannel plasma reactor at atmospheric pressure
… dissociation rate of ~70 g/kWh. Additionally, optical emission spectra in UV and visible regions show the evidence of CO2 dissociation. This thesis compares favorably to other methods, even those operating at sub-atmospheric pressures, and is achieved here at atmospheric and even …

Eigenschaften von Silber-Nanodrähten
… structure.2) Observation of the nanowires by optical darkfield microscopy, and, for comparison, by SEM and TEM. Selection of single, isolated wires was successful by micro-manipulation. The wires were either deposited on quartz glass substrates or they were prepared as free wires which were …

Hydrogen gas generation by water vapor dissociation in an Al/Al2O3 microchannel plasma device
… energy efficiencies ≤ 2 %. Additionally, spectra of the Hα line are used to calculate electron densities, which are in the vicinity of 1.5 ± 0.2 × 1016 cm-3, while spectra of the OH(A-X) transition show a distinctly non-equilibrium population distribution in the OH(A2Σ+) state. Al/Al2O3 …

Fabrication of InGaP LEDs on a graded buffer substrate
… poor electrical conductivity and minimal light emission if any. The development of graded buffer substrates has enabled the lattice matching of semiconductor materials whose lattice constants are significantly different 2. Layers of incrementally changing percent composition are deposited on a …
