The obtained nonlinear CVC are found to exhibit a pronounced (and practically temperature independent) crossover at some current I_{cr}=\\left(\\frac{1}{2\\beta_C}-1\\right)I_C from a resistance R dominated state with V_R=R\\sqrt{I^2-I_C^2} below I_{cr} to a capacitance C dominated state with V_C=\\sqrt{\\frac{\\hbar}{4eC}} \\sqrt{I-I_C} above I_{cr}.
