• Electron tunneling from In As ∕ Ga As quantum dots has been studied by deep level transient spectroscopy (DLTS). Comparing DLTS data with theory, we demonstrate how the results can be interpreted for situations where the emission mechanism is pure tunneling. An illusory anomalous tunneling dependence on electric field is resolved by taking into account the energy level distribution originating from size fluctuations in the quantum dot ensemble.
