Effects of hydrogen dissociation during gas flooding on formation of metal hydride cluster ions in secondary ion mass spectrometry
Jernej Ekar, Sabina Markelj, Miran Mozetič, Rok Zaplotnik, Janez Kovač
Izvirni znanstveni članek
Oznake: hydrogen atmosphere;molecule dissociation;gas flooding;cluster ions;secondary ion mass spectrometry;
The application of hydrogen flooding was recently shown to be a simple and effective approach for improved layer differentiation and interface determination during secondary ion mass spectrometry (SIMS) depth profiling of thin films, as well as an approach with potential in the field of quantitative ...

Are perovskite solar cell potential-induced degradation proof?
Kristijan Brecl, Marko Jošt, Matevž Bokalič, Jernej Ekar, Janez Kovač, Marko Topič
Izvirni znanstveni članek
Oznake: perovskitne sončne celice;napetostno vzbujena degradacija;stabilnost;zunanje delovanje;perovskite solar cells;potential-induced degradation;stability;field operation;
Potential induced degradation (PID) is a solar cell related degradation mechanism due to high potential difference in a photovoltaic (PV) module between the solar cells and its grounded frame. This type of degradation is well known for silicon PV, however, for perovskites it has not been thoroughl ...

Rapid oxidation of adsorbed organic impurities on stainless steel by treatment with diluted peroxynitric acid
Jernej Ekar, Miran Mozetič, Janez Kovač, Nina Recek, Satoshi Ikawa, Katsuhisa Kitano
Izvirni znanstveni članek
Oznake: oksidne plasti;peroxynitric acid;surface modifications;secondary ion mass spectrometry;
Stainless steel forms a native film of mixed metal oxides, and organic impurities are likely to adsorb on the surface upon exposure to ambient conditions. For many applications, oxides and impurities should be removed, and several techniques have been used for decades. An innovative method is presen ...

Recombination of oxygen atoms on the surface of oxidized polycrystalline nickel—temperature and pressure dependences
Domen Paul, Miran Mozetič, Rok Zaplotnik, Jernej Ekar, Alenka Vesel, Gregor Primc, Denis Đonlagić
Izvirni znanstveni članek
Oznake: heterogenous surface recombination;recombination coefficient;nickel;nickel oxide;temperature;
The recombination of neutral oxygen atoms in the ground state on the oxidized nickel samples was studied experimentally in the range of pressures where the maximum density occurs in weakly ionized low-pressure oxygen plasma, i.e. between 40 and 200 Pa. The recombination coefficient was determined in ...

Loss of oxygen atoms on well-oxidized cobalt by heterogeneous surface recombination
Domen Paul, Miran Mozetič, Rok Zaplotnik, Jernej Ekar, Alenka Vesel, Gregor Primc, Denis Đonlagić
Izvirni znanstveni članek
Oznake: materiali;preizkušanje;kinetika;organski materiali;
Calorimetry is a commonly used method in plasma characterization, but the accuracy of the method is tied to the accuracy of the recombination coefficient, which in turn depends on a number of surface effects. Surface effects also govern the kinetics in advanced methods such as atomic layer oxidation ...

Oznake: polytetrafluoroethylene;fluorine depletion;hydrogen plasma;VUV radiation;surface modification;hydrophilic;
Defluorination of polytetrafluoroethylene (PTFE) surface film is a suitable technique for tailoring its surface properties. The influence of discharge parameters on the surface chemistry was investigated systematically using radio-frequency inductively coupled H$_2$ plasma sustained in the E- and H- ...
