Long–lived femtosecond photon echo in thin films on localized exciton states at room temperature

Long–lived femtosecond photon echo in thin films on localized exciton states at room temperature

Long–lived femtosecond photon echo was excited at room temperature in a two–photon regime on the charged exciton states (trion type) localized on the surface defects of a three–layer textured ZnO/Si(B)/Si(P) film with the thickness of each layer at 100 nm in a longitudinal uniform magnetic field.
