Phonon scattering of hot electrons in intense mid-infrared laser fields

We calculated intravalley and intervalley phonon scattering rates of accelerated electrons under intense midinfrared laser fields. We extended the Keldysh theory, which assumes oscillatory motion of Bloch electrons driven by intense laser fields, to phonon scattering of electrons in semiconductors....

Summary:We calculated intravalley and intervalley phonon scattering rates of accelerated electrons under intense midinfrared laser fields. We extended the Keldysh theory, which assumes oscillatory motion of Bloch electrons driven by intense laser fields, to phonon scattering of electrons in semiconductors. We find that phonon emission is possible even if the initial electron energy is less than the phonon energy due to multi‐photon absorption processes. We also find that the scattering rates increase with electric field strength and wavelength. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
