We developed a quantum theory of generation of coherent confined acoustic phonons by one-dimensional electrons drifting in a quantum wire. A general formula for the factor of amplification of the phonon flux, α, is derived. When the electron drift velocity, Vd, is greater than the sound phase veloci...
