Magnetic field dependence of activation energies in the fractional quantum hall effect

Published

Journal Article

We have studied the temperature dependence of the fractional quantum Hall effect at Landaulevel filling factors =13, 23, 43, 53, 25, and 35 in magnetic fields up to 28 T to determine the magnitude of the associated energy gaps. The data suggest a single activation energy for =13, 23, 43, and 35. Its magnitude, much smaller than predicted by current theories, vanishes for B6 T and saturates at B18 T. The data also suggest a single activation energy for =25 and 35 which is smaller than predicted. © 1985 The American Physical Society.
