Abstract

By the method of capacitance spectroscopy and of magnetotransport we have investigated the v = 1/3 and 2/3 fractional-quantum-Hall-effect (FQHE) states in gated GaAs/AlGaAs heterojunctions with tuned electron areal density. Our experimental results confirm the theoretical prediction of the fractional quasiparticle charge e* = e/3 in the v = 1/3 FQHE state and of the existence of spin-aligned quasiholes and spin-reversed quasielectrons in the fully spin-polarized v = 2/3 FQHE state.
