An atomic-scale view at Fe4N as hydrogen barrier material
Aleksander Albrecht, Sang Yoon Song, Chang-Gi Lee +9
Hydrogen, while a promising sustainable energy carrier, presents challenges such as the embrittlement of materials due to its ability to penetrate and weaken their crystal structur…
Microstructure, grain boundary evolution and anisotropic Fe segregation in (0001) textured Ti thin films
Vivek Devulapalli, Marcus Hans, Prithiv T. Sukumar +3
The structure and chemistry of grain boundaries (GBs) are crucial in determining polycrystalline materials' properties. Faceting and solute segregation to minimize the GB energy is…
-guided X-ray photoelectron spectroscopy quantification of Ti vacancies in TiON thin films
Pavel Ondračka, Marcus Hans, Damian M. Holzapfel +3
calculations were employed to investigate the effect of oxygen concentration dependent Ti vacancies formation on the core electron binding energy shifts in cub…
Electronic excitation of transition metal nitrides by light ions with keV energies
Barbara Bruckner, Marcus Hans, Tomas Nyberg +3
We investigated the specific electronic energy deposition by protons and He ions with keV energies in different transition metal nitrides of technological interest. Data were obtai…
