Evidence of intervalley scattering of electrons in the extrinsic photoconductivity of n-type silicon

View publication

Abstract

The extrinsic photoconductivity of n-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. © 1969 The American Physical Society.
