Abstract
The extrinsic photoconductivity of -type silicon has revealed dips in its spectral response due to transfer of electrons among the equivalent conduction-band valleys by intervalley phonon emission. Intervalley LA phonons of energy 26.9 and 47.4 meV (±0.5 meV) are observed to contribute approximately equally to the total scattering of electrons.
