摘要：

We present results on the dynamics of the charging of arrays of InAs self-assembled quantum dots (SAQD's). An equivalent circuit used for metal-insulator-semiconductor-field-effect transistor structures is applied and successfully predicts the observed behavior of the capacitance and conductance dependence on the excitation frequency. The Coulomb blockade effect also plays a role in the frequency-dependent spectra. A Coulomb blockade in this system was observed in arrays of over 10(7) SAQD's, demonstrating the good size uniformity of such a system.
