Application of 7N In as secondary cathode for the direct current-glow discharge mass spectrometry analysis of solid, fused high-purity quartz
Busam, Jochen; Stokkan, Gaute; Muggerud, Astrid Marie F; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2021)Direct current glow discharge mass spectrometry with an indium-based secondary cathode technique is used to analyze solid, nonconducting, fused high-purity quartz regarding metallic impurities of relevance to the solar ... -
Silicon and indium as secondary cathodes for the analysis of solid alumina and sapphire by slow-flow direct-current glow discharge mass spectrometry
Busam, Jochen; Paudel, Gagan; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2022)We demonstrate and compare the capabilities of indium and silicon as secondary cathodes for the analysis of flat, solid alumina and sapphire matrices by direct current glow discharge mass spectrometry (dc-GDMS). The mask ... -
Structural Characterization of Natural Quartz by Scanning TEM
Busam, Jochen; Wenner, Sigurd; Muggerud, Astrid Marie; Van Helvoort, Antonius (Journal article; Peer reviewed, 2018)For quartz, despite its industrial importance and an extensive amount of research done on it, there are still open fundamental questions, e.g. regarding crystal defects, phase changes or damage mechanisms under ionizing ... -
TEM characterization of high-purity quartz
Busam, Jochen (Master thesis, 2017)The PV industry requires high-purity quartz for the production of crucibles for mono crystalline silicon production. Even the smallest amounts of impurities can degrade the performance of photodiode wafers, therefore a ...
