The electric field of an electron in a electron-hole plasma with degenerate electrons. Possibility of formation of a superconductivity state — •Saltanat P. Sadykova¹ and Anri A.

We consider the possibility of formation of a superconductivity state either in a semiconductor or in a electronhole plasma with the degenerate electrons due to the attractive forces between the electrons as a result of the exchange effects through the electron-hole sound wave [1] by analogy to the phonon waves in a solid state. We have determined the view of an interaction potential between two electrons in a degenerate electron-hole plasma. The potential appears to be attractive at distances large than the Debye radius and decreases as 1/r³. We discuss the conditions at which the bound electron state - so called “Cooper Pair” in a such field can be formed.
