  The stability of high-pressure phases of P has been studied using density
functional theory and the local density approximation. Using a linear response
technique, we have calculated the phonon spectrum and electron-phonon
interaction for bcc P and predict it to be superconducting with $T_c$ of 19 K.
We propose that this phase might be realized in epitaxial thin films using
templates such as V(100), Fe(100) or Cr(100) relevant to spintronics
applications.
