요약 | Recently great research effort has been put toward the study of strongly correlated electron systems, of particular interest is the intriguing quantum phases at half-filled Landau levels (LL), including the exotic fractional quantum Hall state ( |
요약 | Chapter 2 and 3 of this thesis focus on physics related with filling factor nu = 5/2. As the lack of correlation between mobility and Delta 5/2, the excitation gap of nu = 5/2 FQHS, has been well established in previous experiments, our work aim |
요약 | In Chapter 3, we define, analyze and discuss the utility of a different metric rho5/2, the resistivity at nu = 5/2 measured at T = 0.3 K, as a high temperature predictor of Delta5/2. This high-field resistivity reflects the scattering rate of c |
요약 | Chapter 4 represents the study of anisotropic transport in high Landau levels. Theory has predicted the existence of a liquid crystal smectic phase that breaks both rotational and translational symmetries in the quantum Hall regime. However, pre |
요약 | Chapter 5 discusses temperature-induced transport asymmetry of both the zero-bias magnetoresistance Rxx and the differential resistance dVxx/dI along the hard transport direction around filling factor nu = 9/2 . At high temperature, T = 100 mK, |
