Thermopower of a 2D electron gas in suspended AlGaAs/GaAs heterostructures
M. Schmidt, G. Schneider, Ch. Heyn +2
We present thermopower measurements on a high electron mobility two-dimensional electron gas (2DEG) in a thin suspended membrane.We show that the small dimension of the membrane su…

Lateral superlattices as voltage-controlled traps for excitons
S. Zimmermann, A. O. Govorov, W. Hansen +3
We demonstrate the localisation of quantum well excitons in a periodic array of linear traps using photoluminescence experiments. The excitonic traps are induced by applying spatia…
