摘要：

In-plane-gated quantum point contacts were fabricated in a pseuudomorphic GaAs/InGaAs/AlGaAs heterostructure by focused ion beam implantation of 100 keV Ga+ ions. We see an intricate conductance quantization structure at 4.2 K. As the temperature is increased, the quantatization becomes less pronounced but clear remnants are observed even at liquid nitrogen temperature and above.
