We study the magneto-transport properties of a quasi-ID GaAs/AlxGa1-xAs ring of mobility 40 000 cm2/V·a at 4 K. The inelastic scattering length is about 4000 Å while the sample length is of the order of 3 μm, so that we are in the diffusive regime. A variety of quantum interference phenomena are observed, including negative magneto-resistance, hole Aharonov-Bohm effect, and aperiodic/quasiperiodic resistance fluctuations. This rich variety enables us to estimate the sample conducting width and electron phase coherence length, lθ, so that we may attempt to obtain a consistent picture of these related phenomena. In addition, we obtain a magnetic field scale on which the hole oscillations disappear. © 1987.
