MOS Capacitor. If i have a MOS capactitor with: tox=0,1 µm, T=300 K, N_D= 10¹⁵cm^-3 . Supposing ideal contact, and null flat band potential V_FB=0 V. How do I find the substratum electric potential (φ_n)?

How do I obtain the depletion region width in micrometers when the surface potential of the interface between Silicon and Oxide φ(x=0) =φ_S its equal to reverse substrate potential (φ_S= - φ_n)? Is there an electric field E_s under the same condition of (φ_S= - φ_n) ?

Can V_GB=V_T in (φ_S= - φ_n)?

Given a MOS capacitor on an n-type semiconductor (relative permittivity =10, ND= 1E13 cm-3)and using an unknown gate dielectric (relative permittivity εr=25). Sketch the C-V plot and label the accumulation, depletion, inversion regions, and the approximate location of the flatband and threshold voltages. Calculate the dielectric thickness and the depletion width in inversion given that the high-frequency capacitance is 250 nF/cm^2 in accumulation and is 50 nF/cm^2 at onset of strong inversion (where minimum capacitance exists). [Ans: dielectric thickness: 88.5...
