Chapter 1Introduction

Frieß, Benedikt

Pages: 1 –5

[The motion of electrons in a three-dimensional solid state system is generally characterized by numerous degrees of freedom spanning a large phase space. Despite the vast number of microscopic states, the overall macroscopic behavior of such systems is often rather simple and can in most cases...

Chapter 2The Two-Dimensional Electron System

Frieß, Benedikt

Pages: 7 –45

[At the heart of this thesis are the properties of high-quality two-dimensional electron systems when being exposed to strong magnetic fields and low temperatures. In our case, the 2DES is hosted inside of a GaAs/AlGaAs heterostructure—a system well known for its excellent quality. Details on the...

Chapter 3Electron–Nuclear Spin Interaction in the Quantum Hall Regime

Frieß, Benedikt

Pages: 47 –68

[The spin degree of freedom only played a minor role in the introduction to the integer and fractional quantum Hall effect given in the previous chapter. It is not essential to understand the formation of quantum Hall states. However, when taking a deeper look into quantum Hall physics, the...

Chapter 4The Spin Polarization of the State

Frieß, Benedikt

Pages: 69 –79

[In the previous chapter, we exploited the hyperfine coupling of electrons and nuclei to investigate different electronic spin excitations. In this chapter, we rely on a different aspect of the hyperfine interaction, namely the ability to probe the electron spin polarization by a nuclear magnetic...

Chapter 5Probing the Microscopic Structure of the Stripe Phase at

Frieß, Benedikt

Pages: 81 –91

[In the previous chapter, we probed the electron spin polarization by means of resistively detected NMR. It was shown that the resonance lineshape not only depends on the spin polarization but also on the spatial distribution of the electrons inside of the quantum well. This technique can...

Chapter 6Surface Acoustic Wave Study of Density-Modulated Phases

Frieß, Benedikt

Pages: 93 –109

[The existence of density-modulated phases was first inferred from signatures in charge transport experiments (Cooper et al. Phys. Rev. B 60, 285, 1999) [1], (Lilly et al. Phys. Rev. Lett. 82, 394, 1999) [2]. The bubble phase was identified by a reappearance of the integer quantum Hall effect,...

Chapter 7Summary

Frieß, Benedikt

Pages: 111 –115

[More than 30 years after its discovery, the quantum Hall effect keeps surprising us by the stunning richness and complexity of the underlying physical phenomena. Some of the finest pieces of many-body physics are featured in the quantum Hall effect. In the light of the magnificent physics...
