Computational framework for metastable materials discovery: integrating kinetics and accurate properties
Computational crystal structure prediction has led to the discovery and experimental realization of many new materials with exceptional properties and technological promise. One of the remaining challenges in computational materials discovery is the prediction of metastable materials: long-lived …

Infrared photoconductive PbTe film processing and oxygen sensitization
… lift-off process. PbTe films displayed an FCC rocksalt structure and slight preference for (200) texture when thermally deposited on a Si substrate. A 250-nm thick sample exhibited large photoconductivity, with responsivity higher than 100 V/W between 2-3 [mu]m wavelengths, a factor of 4 higher …

Chalkogenidlegierungen für optische und elektronische Speichermedien
… of optical and electrical properties with the structure of these alloys. The GeSbTe alloys under investigation showed a thermally activated conductivity in the amorphous phase. The corresponding activation barrier was around 0.4 eV while the resistivity was about a few Wmat room temperature. …

Quantum chemical calculations of transition metal oxynitrides
… of the other oxynitrides are predicted. The structure changes from the rocksalt structure for the early 3d transition-metal oxynitrides Sc-Mn to the zinc blende structure for the later ones Fe-Ni. This phenomenon can be explained in a qualitative way by a detailed chemical bonding analysis …

Strukturelle und kinetische Aspekte der kombinatorischen Materialsynthese am Beispiel der Phasenwechselmedien
… to predict the energetically favored crystal structure of an alloy. The influence of the crystal structure on the kinetics of the phase transformation and of the coordination number and the band gap on the optical properties was discussed. To this end, AgInTe and AgSbTe alloys were …

Plastic Deformation in Complex Crystal Structures
Many materials with complex crystal structures have attractive properties, including high specific strength, good creep resistance, oxidation resistance, often through high silicon or aluminium content. This makes them of interest for high temperature structural applications, but the use of many …
