Abstract (German)

Diese Arbeit behandelt die Herstellung hochbeweglicher zweidimensionaler Lochsysteme (2DHG) in GaAs/AlGaAs Heterostrukturen mittels Molekularstrahlepitaxie (MBE) und deren Charakterisierung durch Magnetotransportuntersuchungen bei tiefen Temperaturen zwischen 4 K und 30 mK. Im Mittelpunkt liegt hierbei die Optimierung von Ladungsträgerbeweglichkeiten. Dies wird erreicht durch die Einführung einer ...


Translation of the abstract (English)

This thesis outlines the fabrication of high mobility two-dimensional hole-gases (2DHG) in GaAs/AlGaAs heterostructures with molecular beam epitaxy (MBE) and their characterization with magnetotransport measurements at low temperatures between 4 K and 30 mK. Here the optimization of the carrier mobility is focused. This will be achieved by introducing a novel carbon-filament doping source, with ...
