| Research Abstract |
The purpose of this research is to detect the interlayer coherence of the bilayer quantum Hall effect by fabricating an independent-contact bilayer sample. We have proceeded the sample fabrication in collaboration with Prof. W. Dietche, member of Prof. K. von Klitzing's group, Max Planck Institute in Stuttgart. However, we could not do the experiment for the detection of the interlayer coherence because the resistance diverges in the magnetic field due to some inappropriate ohmic-contact pins in the sample. Nevertheless, we have established the measurement system up to now, so that we can continue this research by renewing the sample.
