摘要: Using frequency-dependent capacitance spectroscopy, the dynamics of tunneling into arrays self-assembled InAs quantum dots is investigated with respect to sample geometry, Coulomb interaction, and magnetic field. An equivalent resistance-capacitance circuit derived which allows us determine times for each state dots. The different many-particle states are explained by a reduced barrier interaction. A field applied perpendicular direction results in strong suppression charging signal, attributed enhanced localization caused Calculations three-dimensional zero-dimensional magnetotunneling can account experimental data.
