Abstract
The selective excitation and detection of quantum Hall edge states has opened access to several interesting phenomenons, two of which are addressed in this paper: Firstly we conducted time-resolved current measurements of edge magnetoplasmons. At filling factors close to ν = 3 we observe two decoupled modes of edge excitations, one of which is related to the innermost compressible strip and is identified as an inter-edge magnetoplasmon mode. From the analysis of the propagation velocities of each mode the internal spatial parameters of the edge structure are derived. Secondly we have studied the tunnelling between spin polarised edge states at high magnetic fields up to 28 T. Measurements of the inter-edge I-V characteristic in tilted magnetic fields B allow to determine the effective g-factor g* (B). We also observe a dynamical nuclear.
