Abstract
Experiments on Hall-bar samples with a cross-gate give quantized values of the resistance for integer filling factors. For non-integer filling factors a strong dependence on sample geometry is found. We get a different coupling between gate voltage induced edge states of different levels. A non-equilibrium population of edge states can also be observed for narrow and long Hall-bar samples with good contacts.
