Photoinduced ultrafast electron injection from a surface attached molecule: Control of electronic and vibronic distributions via vibrational wave packets

Abstract

Photoinduced femtosecond electron transfer from a chromophore attached via a molecular group to a semiconductor surface is discussed theoretically. For an early time region after ultrafast photoexcitation and for a specific range of electron transfer times, the occurrence of remarkable electronic and vibrational distributions is proposed. The energetic structure and range of the related electronic wave packets can be controlled by the shape of a vibrational wave packet which has been prepared by laser excitation of the attached molecule.
