Is it possible to define a flat band voltage for the Schottky diodes?

In just the same way that we define the flat band voltage of a MOS capacitor, can we get a flat band condition for a Schottky diode?

How can the Fermi levels of M an S get aligned and thermal equilibrium established when an MOS capacitor is fabricated ?

In the ideal case the oxide in an MOS capacitor is of infinite resistance. Hence charge carriers cannot flow from metal to semiconductor.Can someone help? Regards and thanks.

What is the importance of the x-intercept of 1/C^2 vs gate voltage of an MOS capacitor?

I am studying some aspects of MOS caps with aluminum oxide as the gate oxide. I have read in some articles that x-intercept of 1/C^2 vs gate voltage (Vg) gives flat band voltage (Vfb). But this...
