Direct phonon excitation in semiconductors by ultrashort intense THz radiation

Not Accessible

Your library or personal account may give you access

Abstract

Ultrashort intense THz radiation generated through laser filamentation in air is employed to directly excite the lattice of AlGaAs semi-insulating crystals. Incoherent as well as coherent phonons are shown to be excited in this way.
