We report on detailed experimental studies of a high-quality heterojunction insulated-gate field-effect transistor (HIGFET) to probe the particle-hole symmetry of the fractional quantum Hall effect (FQHE) states about half-filling in the lowest Landa

We report in this Rapid Communication an antilevitation behavior of Landau levels in vanishing magnetic fields in a high quality heterojunction insulated-gated field-effect transistor. We found, in the Landau fan diagram of electron density versus ma

We report the results of tilted magnetic field experiments on three high quality wide GaAs quantum wells, with particular emphasis on the N ≥ 1 Landau levels. With an increasing component of in-plane magnetic field, B∥, we observe reentrant behav

We present a fabrication process and results of transport measurements of a number of p-channel heterojunction-insulated-gate field-effect transistors (HIGFETs). Without intentional doping in HIGFETs, the disorder is likely to be less than that in th

Wigner solids in two-dimensional electron systems in high magnetic field B exhibit a striking, microwave or rf resonance, that is understood as a pinning mode. The temperature, Tm, above which the resonance is absent, is interpreted as the melting te

We report measurements of microwave spectra of two-dimensional electron systems hosted in dilute Al alloy ${\mathrm{Al}}_{x}{\mathrm{Ga}}_{1\ensuremath{-}x}\mathrm{As}$ for a range of Landau level fillings $\ensuremath{\nu}$ around 1. For $\ensuremat

We have carried out a systematic study of the tilted magnetic field induced anisotropy at the Landau level filling factor \nu=5/2 in a series of high quality GaAs quantum wells, where the setback distance (d) between the modulation doping layer and t

We present in this Letter the results from two high quality, low density GaAs quantum wells. In sample A of electron density n=5.010 10 cm -2 , anisotropic electronic transport behavior was observed at =7/2 in the second Landau level. We believ

Recent experiments have shown that two-dimensional electron systems with an externally applied magnetic field are an extremely rich ground for many-body physics. In particular, when only two of the Landau levels (LL) are filled an intricate magnetore
