Abstract = {Transport measurements are presented on a class of electrostatically defined lateral dots within a high mobility two-dimensional electron gas (2DEG). The design allows Coulomb blockade (CB) measurements to :' be performed on a single lateral dot containing 0, 1 to over 50 electrons. The CB measurements are enhanced by the spin polarized injection from and into 2DEG magnetic edge states. This combines the measurement of charge with the measurement of spin through spin-blockade spectroscopy. The results of Coulomb and spin-blockade spectroscopy for the first 45 electrons enable us to construct the addition spectrum of a lateral device. We also demonstrate that a lateral dot containing a single electron is an effective local probe of a 2DEG edge. {\copyright}2000 The American Physical Society.},
