Empirical atom model of Vegard's law
Lei Zhang,Lei Zhang,Shichun Li +2 more
TL;DR: In this article, an empirical atom model of Vegard's law has been proposed to account for signs of deviations according to the electron density at Wigner-Seitz cell from Thomas-Fermi-Dirac-Cheng model.
Journal ArticleDOI
Optical properties of SiGe alloys
Rajeev Ahuja,Clas Persson,A. Ferreira da Silva,J. Souza de Almeida,C. Moyses Araujo,B. Johansson +5 more
TL;DR: The optical properties of Si1-xGex have been investigated theoretically using a full-potential linear muffin-tin-orbital method as mentioned in this paper, and the density-of-states as well as the real and imaginary parts of the dielectric function were calculated.
Journal ArticleDOI
NMR and ESR relaxation in Nd- and Gd-doped LaPO4: towards the accurate determination of the doping concentration
TL;DR: The comparison between nuclear and electronic relaxation suggests that Nd-Gd codoping may improve the efficiency of the Gd(3+) ion as a relaxing agent in MRI (magnetic resonance imaging) techniques.
Journal ArticleDOI
Polarization induced interface and electron sheet charges of pseudomorphic ScAlN/GaN, GaAlN/GaN, InAlN/GaN, and InAlN/InN heterostructures
Oliver Ambacher,Oliver Ambacher,Björn Christian,M. Yassine,M. Baeumler,Stefano Leone,Ruediger Quay +6 more
TL;DR: In this paper, the piezoelectric and spontaneous polarization induced surface and interface charges determined to the ones predicted and measured in heterostructures with GaxAl1−xN and InxAl1+xN barriers are compared.
Journal ArticleDOI
