comment Can surface dipoles/charges change the work function of a metal?
I see, thanks. There is no marks for conduction band in the metal at all. The blue line is the Fermi level. So the band is not filled completely.

Could you show one of those simplified band diagrams? If entire band is filled it is not a conduction band, it is a valence band. And in this case it is a dielectric not metal.

Yes there will be gravitational field gradient, it can be derived from equation (1). As for stability, I'm going to add some explanations concerning liquid cover to my answer.

Are you sure there is $\phi_n(t)\exp(-iE_nt)$ not just $\phi_n\exp(-iE_nt)$?
