What is Dynamics of the Electron–hole Correlation in Femtosecond Pulse Excited Semiconductors about?
We study the temporal evolution of the spatial electron-hole correlation after a resonant femtosecond (fs) pulse excitation. The probability of finding an electron and hole at a distance r peaks at r 0; because the absorption process creates the electron-hole pair at the same position but with opposite momenta. The correlation extends also for unbound electron-hole pairs over a sphere with roughly an exciton Bohr radius. Due to the resulting drift, but also due to carrier-carrier and carrier-LO-phonon scattering, the original correlation decreases in about 100 fs and approaches its constant value. The evolution of the electron-hole correlation is calculated within the semiconductor Bloch equations with quantum kinetic scattering integrals due to time-dependently screened Coulomb and LO-phonon scattering integrals.
