Critical thickness calculations for InGaN/GaN
TL;DR: In this paper, a model based on the overall energy balance was used to calculate the critical thickness for an InGaN epitaxial layer on a GaN substrate, which was found to be lower than values predicted by models proposed by Fischer or People and Bean.
Journal ArticleDOI
Ab initio inspired design of ternary boride thin films.
V. Moraes,Helmut Riedl,Christoph Fuger,Peter Polcik,Hamid Bolvardi,David Holec,Paul H. Mayrhofer +6 more
TL;DR: Investigations on the brittle-ductile behavior of the various diborides reveal, that the metastable structures are more ductile than their stable counterparts (WB2, TcB2, etc.).
Journal ArticleDOI
Decomposition pathways in age hardening of Ti-Al-N films
Richard Rachbauer,S. Massl,Erich Stergar,David Holec,Daniel Kiener,Jozef Keckes,Jörg Patscheider,M. Stiefel,Harald Leitner,Paul H. Mayrhofer +9 more
TL;DR: In this paper, the combined effect of annealing time and temperature upon the nano-structural development of Ti0.46Al0.54N thin films is studied, with a thermal exposure of either 1 min or 120 min in 100°C steps from 500°C to 1400°C. The impact of chemical changes at the atomic scale on the development of micro-strain and mechanical properties is studied by postannealing investigations using X-ray diffraction, nanoindentation, 3D-atom probe tomography and high-resolution...
Journal ArticleDOI
Trends in the elastic response of binary early transition metal nitrides
TL;DR: In this article, the elastic response of nine binary early transition metal nitrides (ScN, TiN, VN, YN, ZrN, NbN, LaN, HfN, and TaN) and AlN were studied.
Journal ArticleDOI
Intermetallic β‐Solidifying γ‐TiAl Based Alloys − From Fundamental Research to Application
Svea Mayer,Petra Erdely,Franz Dieter Fischer,David Holec,Michael Kastenhuber,Thomas Klein,Helmut Clemens +6 more
TL;DR: In this article, a review of the development of the titanium alloy through structural characterization with sophisticated in and ex situ methods, engineering properties, manufacturing, and processing technologies to all aspects of application is presented.
