Detection of intra-band gap defects states in spin-coated sol-gel SnOx nanolayers by photoelectron spectroscopies
Grządziel, Lucyna; Krzywiecki, Maciej; Szwajca, Anna; Sarfraz, Adnan; Genchev, Georgi; Erbe, Andreas (Journal article; Peer reviewed, 2018)The presence of occupied intra-band gap states in oxygen-deficient tin dioxide (SnO x ; 1 < x < 2) is crucial for efficient manufacturing of multipurpose electronic devices based on transparent conducting oxides. Former ... -
Effect of order and disorder on degradation processes of copper phthalocyanine nanolayers
Grzadziel, Lucyna; Krzywiecki, Maciej; Genchev, Georgi; Erbe, Andreas (Journal article; Peer reviewed, 2017)The impact was examined of surface ordering of 50 nm-thick copper phthalocyanine (CuPc) layers on the layer's susceptibility to ambience-induced degradation processes. The surface morphology of CuPc layers obtained by ... -
Raman spectroscopy of mackinawite FeS in anodic iron sulfide corrosion products
Genchev, Georgi; Erbe, Andreas (Journal article; Peer reviewed, 2016)Raman spectroscopy in a confocal microscope was used to study electrochemically synthesized corrosion products from sour gas experiments. When exposed to oxygen-containing atmosphere, the initial mackinawite FeS corrosion ... -
Role of molybdenum in corrosion of iron-based alloys in contact with hydrogen sulfide containing solution.
Genchev, Georgi; Bosch, Christoph; Wanzenberg, Elke; Erbe, Andreas (Journal article; Peer reviewed, 2017)A sample iron molybdenum alloy with 3.4 wt% (2 at%) molybdenum, and pure iron, are exposed to hydrogen sulfide saturated saline solution for up to 56 days. In addition, their behavior under anodic polarization in the same ... -
Sour Gas Corrosion—Corrosion of Steels and Other Metallic Materials in Aqueous Environments Containing H2S
Genchev, Georgi; Erbe, Andreas (Chapter, 2013)The corrosion of metals, mainly steels, in contact with H2S-containing solutions is a general problem especially in gas and oil production. The corrosion products are hydrogen and iron sulfides. Penetration of the hydrogen ...
