Experimental studies of the fractional quantum Hall effect in the first excited Landau level
W. Pan, J. S. Xia, H. L. Stormer +7
We present a spectrum of experimental data on the fractional quantum Hall effect (FQHE) states in the first excited Landau level, obtained in an ultrahigh mobility two-dimensional…
Quantization of the diagonal resistance: Density gradients and the empirical resistance rule in a 2D system
W. Pan, J. S. Xia, H. L. Stormer +7
We have observed quantization of the diagonal resistance, R_xx, at the edges of several quantum Hall states. Each quantized R_xx value is close to the difference between the two ad…
Tilt Induced Localization and Delocalization in the Second Landau Level
G. A. Csathy, J. S. Xia, C. L. Vicente +6
We have investigated the behavior of electronic phases of the second Landau level under tilted magnetic fields. The fractional quantum Hall liquids at 2+1/5 and 2+4/5 and the s…
Electron correlation in the second Landau level; a competition between many, nearly degenerate quantum phases
J. S. Xia, W. Pan, C. L. Vincente +7
At a very low temperature of 9mK, electrons in the 2nd Landau level of an extremely high mobility two-dimensional electron system exhibit a very complex electronic behavior. With v…
