Frustration enhanced by Kitaev exchange in a $\boldsymbol{\tilde{j}_{\text{eff}}=\frac12}$ triangular antiferromagnet

Autor: Wellm, C., Roscher, W., Zeisner, J., Alfonsov, A., Zhong, R., Cava, R. J., Savoyant, A., Hayn, R., Brink, J. van den, Büchner, B., Janson, O., Kataev, V.

Publikováno v: Phys. Rev. B 104, L100420 (2021)

Triangular Heisenberg antiferromagnets are prototypes of geometric frustration, even if for nearest-neighbor interactions quantum fluctuations are not usually strong enough to destroy magnetic ordering: stronger frustration is required to stabilize a

Statistical studies of random silicon-germanium alloys using electronic structure calculations

Autor: Roscher, W., Fuchs, F., Wagner, C., Schuster, J., Gemming, S.

Publikováno v: DPG Frühjahrstagung, 31.03.-05.04.2019, Regensburg, Deutschland

Random alloys are relevant for many applications. One example is silicon-germanium which is used for high frequency devices like heterojunction-bipolar transistors. We therefore investigate the electronic structure of Si1−xGex alloys in the entire
