Abstract:

A piezospectroscopic investigation of the normalized wave-length-modulated absorption spectra of the phonon-assisted indirect exciton in Si TO-phonon and Ge LA phonon at 77 deg K has yielded values for the ratio of the electron-phonon to the hole-phonon matrix elements for the gamma-delta Si and gamma-L Ge transitions.
