Real Time Observation of Fano Interference in Si (Current Topics)

Abstract

The progress in femtosecond laser has enabled us to observe coherent motion of lattice vibrations and molecular vibrations in solids. Nevertheless study of coherent phonons in Si, which is an important material for modern devise application, is still missing. We report dynamics of transient interaction of electrons with phonons, followed by generation of coherent optical phonon, observed by using pump-probe technique with 400 nm, 10 fs laser.
