Abstract

The two-terminal conductance of ballistic point contacts in the two-dimensional electron gas of a high-mobility GaAs/AlxGa1–xAs heterostructure has been studied in quantizing electric and magnetic fields. The conductance is found to be quantized at multiples of e2/h, exclusively determined by the number of occupied magnetoelectric subbands in the constriction. The experiment provides the first direct demonstration of magnetic and electric depopulation of one-dimensional subbands in a single wire.
