摘要：

We have studied transport of a two-dimensional electron gas through a potential barrier prepared on shallow GaAs/AlxGa1-xAs/InGaP heterostructure by local anodic oxidation (LAO) with an AFM tip. The potential barrier height after LAO was 55 me V and it increased to 2 70 me V after oxide line removal at 300 mV, at room temperature. Barriers with this height can be used for room temperature nanometre-sized structures and devices fabrication.
