1. Quantum dots: photodetectors, weak localization and counter-rotating edge states / Pontos-quânticos: fotodetectores, localização-fraca e estados de borda contra-rotativos
In this work we present transport properties of heterostructures with quantum-dots. Three subjects were exploited: on the first one, we observed anomalous quantum Hall plateaus, for wich we attributed to the existence of counter-rotating edge-states; on the second subject, we determined the decoherence time of the bidimensional electron system as a function
