Abstract

The density functional theory is used for the determination of a ground state of a quasi-two-dimensional electron $-$ hole liquid (EHL) in the presence of an external electric field. The Kohn $-$ Sham equations for electrons and holes are numerically solved. The binding energies of electron $-$ hole pair are calculated for various silicon surfaces. It is shown that EHL can exist on the (111) Si.
