Abstract
It is shown that attractive electron-electron interaction arising from the exchange of two optical phonons is a possible mechanism for superconductivity in some degenerate semiconductors. This mechanism is present independent of whether the semiconductor is many-valley or not. Application to SrTi is discussed.
