Abstract

We have experimentally found that the height of quantized conductance steps of a short constriction in a two-dimensional electron gas can reduce by 3% as compared to 2e2/h. We explain this phenomenon by different shift of one-dimensional subbands in response to changing gate voltage. Both simple analytical estimate and realistic modeling of the device yield the same magnitude of the effect as that in experiment.
