Direct evaluation of spatial distribution of electrons ejected by two-photon ionization of aromatic molecules in ultrathin polymer films
The spatial distribution of electrons ejected by two-photon ionization of aromatic molecules was directly evaluated using a multi-layered structure of ultrathin polymer films where donor (D) and acceptor (A) layers were separated by spacing layers. The results show that electrons ejected by two-photon ionization are mostly captured by an A layer about 2-3 nm away from the D layer.
