Journal ArticleDOI
Toughness enhancement in TiN/WN superlattice thin films
Julian Buchinger,Nikola Koutná,Zhuo Chen,Zaoli Zhang,Paul H. Mayrhofer,David Holec,Matthias Bartosik +6 more
TL;DR: In this article, the authors synthesize a series of transition metal nitride thin films by DC reactive magnetron sputtering and demonstrate a vacancy-stabilised cubic configuration throughout, as well as a marginal lattice mismatch between the TiN and WN layers.
Journal ArticleDOI
Point defects stabilise cubic Mo-N and Ta-N
TL;DR: In this article, the authors employed ab initio calculations to investigate the energetics of point defects in metastable rocksalt cubic Ta-N and Mo-N, and showed that defect-ordered structures are more stable than perfect ones with metal-to-nitrogen stoichiometry.
Journal ArticleDOI
The impact of nitrogen content and vacancies on structure and mechanical properties of Mo–N thin films
TL;DR: In this article, the formation of the NaCl-based γ-MoNx phase is favored for nitrogen concentrations between 23 and 34 at.% (i.e., x = 0.30 − 0.53).
Journal ArticleDOI
Peculiarity of self-assembled cubic nanolamellae in the TiN/AlN system: Epitaxial self-stabilization by element deficiency/excess
Jakub Zalesak,David Holec,I. Matko,Martin Petrenec,Bernhard Sartory,Nikola Koutná,Nikola Koutná,Rostislav Daniel,Reinhard Pitonak,Jozef Keckes +9 more
TL;DR: In this paper, a self-assembled 3.8-μm-thick cubic (c) (Al x Ti 1-x ) y N 1- y film grown by low pressure chemical vapour deposition on a Al 2 O 3 (0001) substrate is discussed.
Journal ArticleDOI
Influence of carbon deficiency on phase formation and thermal stability of super-hard TaCy thin films
Helmut Riedl,T. Glechner,T. Wojcik,Nikola Koutná,Szilárd Kolozsvári,Valentina Paneta,David Holec,Daniel Primetzhofer,Paul H. Mayrhofer +8 more
TL;DR: Using nonreactive sputter deposition allows the preparation of single-phase fcc structured TaCy thin films over a wide compositional range with y between 0.63 and 1.04 as discussed by the authors.
