In this exercise the structure of MgO will be optimised with respect to the free energy at a number of temperatures. The free energy is computed within the quasi-harmonic approximation. A free energy ...

Abstract: The atomic structure of a symmetric 24°[001] tilt grain boundary in MgO has been derived directly from high-resolution Z-contrast images obtained in a scanning transmission electron ...

One of its prerequisites is the ability to inject spin-polarized electrons into semiconductors. An overview is presented of recent progress in spin injection using an injector based on a crystalline ...
