We investigate the local conductivity of a two-dimensional electron gas (2DEG) in the regime of the quantum Hall effect with a scanning capacitance microscope. At integer Landau level filling factors the bulk of the sample is insulating, whilst we find a well-defined narrow stripe of high local cond
Hall and diagonal resistances of bilayer fractional quantum Hall systems are discussed theoretically. The bilayers have electrodes attached separately to each layer. They are assumed to be coupled weakly by interlayer tunneling, while the interlayer Coulomb interaction is negligibly small. It is sho
