    Sammanfattning : The demand for fast and energy efficient (opto-)electronic applications needs high mobility semiconductor materials, such as InAs with a very high electron mobility and GaSb with a very high hole mobility. Beyond the material itself, also an innovative device geometry is needed, for example, the gate-all-around geometry that provides higher efficiency and electrostatic control for computational units.
