Defect-activated interface modes with a large range of possible wave vectors in the superlattice planes, as well as interface modes with a well-defined in-plane wave vector, induced by a titled 80A-period GaAs/AlAs superlattice on the surface of a (G

This work discusses the implementation of a 1.5 MW system that injects the regenerated energy, caused by the braking action of electric trains, back into the Eskom supply. At present this energy is dumped into resistor banks and goes to waste as heat
