Abstract
We have observed conductance fluctuations due to electron interference in a split-gate quantum dot, fabricated in the two-dimensional electr on gas of a GaAs/AlxGa1-xAs heterojunction, We have determined the pha se breaking time of electrons by two independent analyses, using the c orrelation field and the amplitude of the fluctuations. Phase breaking times obtained by these distinct approaches are found to differ from each other by a factor of six. (C) 1997 Academic Press Limited.
