We report an experimental study indicating ultrafast creation and annihilation of space-charge domains in a semiconductor superlattice under the action of a THz field. Our experiment was performed for an InGaAs/InAlAs superlattice with the conduction electrons undergoing miniband transport. We...

Emphasis on the need to reduce the deterrence effects and costs associated with interchange, so that increasingly seamless public transport journeys can be provided, is now a key policy goal. This paper reports the findings from a series of focus groups and in-depth interviews of both public...
