Si. Dorozhkin et al., CAPACITANCE SPECTROSCOPY OF THE FRACTIONAL QUANTUM HALL-EFFECT - TEMPERATURE-DEPENDENCE OF THE ENERGY-GAP, JETP letters, 58(11), 1993, pp. 834-838
The energy gap in the fractional quantum Hall effect has been measured
as a function of the magnetic field and the temperature by the method
of capacitance spectroscopy. Variation of the magnetic field over a b
road range does not affect the temperature dependence of the gap.
