We have investigated by femtosecond pump-and-probe measurements the exciton dynamics in a novel conjugated polymeric heterostructure consisting of regularly alternated thienylenic and phenylenic segments. A fast initial relaxation followed by a power law decay has been observed. The initial part of
By applying a theory developed in previous works we calculate the polar oscillation modes of a DHS (double heterostructure) for the GaAs/AlAs system in the long wavelength limit. The material for each layer of the structure is modeled as an isotropic continuum. We report general analytical solutions
