摘要
We study electron tunnelling from self-assembled InAs quantum dots with time-resolved capacitance measurements at low temperature (T 10 K). Within a simple WKB model the electric field dependence of the tunnelling rate is analyzed. The data reveal that tunnelling emission from s- and p-like quantum dot states can clearly be resolved. The binding energies obtained from a triangular-well model are in good agreement with values obtained with DLTS experiments.
