Quantitative strain analysis of InAs/GaAs quantum dot materials
Per Erik Vullum, Magnus Nord, Maryam Vatanparast +5
Geometric phase analysis has been applied to high resolution aberration corrected (scanning) transmission electron microscopy images of InAs/GaAs quantum dot (QD) materials. We sho…
Lattice thermal conductivity of TiZrHfNiSn half-Heusler alloys calculated from first principles: Key role of nature of phonon modes
Simen N. H. Eliassen, Ankita Katre, Georg K. H. Madsen +3
In spite of their relatively high lattice thermal conductivity , the XNiSn (X=Ti, Zr or Hf) half-Heusler compounds are good thermoelectric materials. Previous studies hav…
Assessing electron beam sensitivity for SrTiO and LaSrMnO using electron energy loss spectroscopy
Magnus Nord, Per Erik Vullum, Ingrid Hallsteinsen +2
Thresholds for beam damage have been assessed for LaSrMnO and SrTiO as a function of electron probe current and exposure time at 80 and 200 kV acceleration…
The effect of turbulent clustering on particle reactivity
Jonas Krüger, Nils E. L. Haugen, Dhrubaditya Mitra +1
The effect of turbulence on the heterogeneous (solid-fluid) reactions of solid particles is studied numerically with Direct Numerical Simulations (DNS). A simplified reaction syste…
