STUDY OF Cu/TiN SYSTEM: WETTING OR NON-WETTING

摘要

Refractory metal carbides and nitrides exhibit partial metallic bonding, which has beneficial repercussions on wetting and adhesion properties with metals. However, in the case of stoichiometric TiC and TiN, diverging experimental results exist going from non-wetting to wetting. For this reason new sessile drop experiments are performed in the model system Cu/TiN in high vacuum and in static atmospheres of gettered He and dry N_2-H_2 mixtures.
