By the method of capacitance spectroscopy and of magnetotransport we have investigated the = 1 3 and 2 3 fractionalquantum-Hall-e ect (FQHE) states in gated GaAs=AlGaAs heterojunctions with tuned electron areal density. Our experimental results conΓΏrm the theoretical prediction of the fractional qua
Huge resistance maxima are observed at certain fractional ΓΏllings of the lowest Landau level of two dimensional electron gases which are conΓΏned to narrow quantum wells. By varying the tilt angle between the sample and the external magnetic ΓΏeld, the e ect is observed only over a certain range of Co
