From single dots to interacting arrays
Vidar Gudmundsson, Andrei Manolescu, Roman Krahne +1
We explore the structural changes in charge the density and the electron configuration of quantum dots caused by the presence of other dots in an array, and the interaction of neig…

Far-Infrared Excitations below the Kohn Mode: Internal Motion in a Quantum Dot
Roman Krahne, Vidar Gudmundsson, Christian Heyn +1
We have investigated the far-infrared response of quantum dots in modulation doped GaAs heterostructures. We observe novel modes at frequencies below the center-of-mass Kohn mode.…
