摘要：

We have studied electron transport properties on an artificial periodic and quasi-periodic array of scatterers. Scatterers are introduced in two-dimensional electron gas of a GaAs-AlGaAs heterojunction by employing electron beam and dry etching, or by damaging of direct focused ion beam irradiation. Novel magnetoresistance oscillations are observed at low magnetic field. It was found that the dominant features in the data arise from commensurate classical orbit.
