Within an one-dimensional tight-binding model, we investigate the inelastic scattering processes of oppositely charged polarons in conjugated polymers under the influence of an external electric field, by using a nonadiabatic evolution method. It is found that the polaron pair does not...

The organic-inorganic combined structural device (ITO/PVK:Eu/ZnS/Al) is fabricated based on layered optimization scheme. II–VI semiconductor material ZnS is acted as an electron function (transporting and acceleration) layer. The hot electrons which have been accelerated in the ZnS layer...

The non-linear photoelectron spectra obtained by short laser pulses from a Ag(100) surface show a high-energy electron emission due to an athermal electron distribution created by the laser pulse. By comparing the photoemission at normal and non-normal emission geometry it is possible to...

The infrared photo-induced spectra of the isotope-substituted stoichiometric La<Subscript>2</Subscript>CuO<Subscript>4</Subscript> samples were studied at T=20 K. Measured spectra were analyzed within the small polaron hopping theory. A small, but detectable shift of the effective phonon frequency on the substitution <Superscript>16</Superscript>O to <Superscript>18</Superscript>O is found...</superscript></superscript></subscript></subscript>
