Electron channeling studies of atom site preference and distribution in doped Mg2Si1-xSnx thermoelectrics
Delimitis, Andreas; Kyratsi, Theodora; Hansen, Vidar Folke (Peer reviewed; Journal article, 2022)The electron channeling effect, i.e., the dependence of the characteristic x-ray emission on the crystallographic direction of the incoming beam in an analytical transmission electron microscope was employed to elucidate ... -
Geometry determination and refinement in the rotation electron diffraction technique
Delimitis, Andreas; Hansen, Vidar; Gjønnes, Jon (Journal article; Peer reviewed, 2019-02)The necessary parameters (rotation axis, incident electron beam direction and beam tilt path) in order to describe the diffraction geometry in the Rotation Electron Diffraction (RED) method during data collection are ... -
Reduction of Hf via Hf/Zr Substitution in Mechanically Alloyed (Hf,Ti)CoSb Half-Heusler Solid Solutions
Ioannou, Ioanna; Delimitis, Andreas; Gelbstein, Yaniv; Kyratsi, Theodora (Peer reviewed; Journal article, 2022)Abstract (Hf,Zr,Ti)Co(Sb,Sn) Solid solutions were prepared by mechanical-alloying followed by hot-press method as an attempt to reduce Hf concentration and therefore the material’s cost without negatively affecting the ... -
Spin injection from EuS/Co multilayers into GaAs detected by polarized electroluminescence
Goschew, A.; Roca, R.C.; Nishizawa, N.; Munekata, H.; Delimitis, Andreas; Fumagalli, P. (Peer reviewed; Journal article, 2019)We report on the successful spin injection from EuS/Co multilayers into (100) GaAs at low temperatures. The spin injection was verified by means of polarized electroluminescence (EL) emitted from AlGaAs/GaAs-based ...
