Comment on Reconciling results of tunnelling experiments on (Ga,Mn)As arXiv:1102.3267v2 by Dietl and Sztenkiel

We comment on the recent paper Reconciling results of tunnelling experiments on (Ga,Mn)As arXiv:1102.3267v2 by Dietl and Sztenkiel. They claimed that the oscillations observed in the d2I/dV2-V characteristics in our studies on the resonant tunneling spectroscopy on GaMnAs, are not attributed to the resonant levels in the GaMnAs layer but to the two-dimensional interfacial subbands in the GaAs:Be layer. Here, we show that this interpretation is not able to explain our experimental results and our conclusions remain unchanged.
