In present work we focus on these problems and on the interpretation of the recent CV data given in W. Lei, C. Notthoff, A. Lorke, D. Reuter and A. D. Wieck (Appl. Phys. Lett. 96, 033111 (2010). We show that a variant of oscillator model used in this paper does not resolve known problem of the c-v measurements: the derived value of the energy-gate-voltage conversion coefficient (f=2) is in a disagreement with that obtained from CV experiments (f=8).
