  • The recently discovered layered copper oxide high-T/sub c/ superconductors are discussed as models of a layered electron gas with highly anisotropic collective modes (layer plasmons). Our view that a combined phonon--plasmon pairing interaction is the mechanism for the high transition temperatures is presented together with the appropriate dielectric function describing the electron collective response. The implications of this model for the interpretation of optical (infrared and optical absorption, reflectivity, and Raman scattering) and related spectroscopies, such as electron and positron loss, are given. In particular, temperature-dependent loss features are shown to arise from the lowest branch of the layer plasmons.
  • As the electron-hole density in Si, and the corresponding plasma frequency, increase to equal or exceed the indirect energy gap, a new recombination channel opens up. We calculate the rate of such a recombination process to first order in the phonon coupling and the emission of a single plasmon. We find that at such high densities (of the order of 10/sup 21//cm/sup 3/) this channel strongly inhibits further increase of the carrier density even a picosecond after the pump-laser pulse.
  • The inclusion of plasmonic nanoparticles into organic solar cell enhances the light harvesting properties that lead to higher power conversion efficiency without altering the device configuration. This work defines the consequences of the nanoparticle overloading amount and energy transfer process between gold nanorod and polymer (active matrix) in organic solar cells. We have studied the hole population decay dynamics coupled with gold nanorods loading amount which provides better understanding about device performance limiting factors. The exciton and plasmon together act as an interacting dipole; however, the energy exchange between these two has been elucidated via plasmon resonance energy transfer (PRET)more » mechanism. Further, the charge species have been identified specifically with respect to their energy levels appearing in ultrafast time domain. The specific interaction of these charge species with respective surface plasmon resonance mode, i.e., exciton to transverse mode of oscillation and polaron pair to longitudinal mode of oscillations, has been explained. Thus, our analysis reveals that PRET enhances the carrier population density in polymer via non-radiative process beyond the concurrence of a particular plasmon resonance oscillation mode and polymer absorption range. These findings give new insight and reveal specifically the factors that enhance and control the performance of gold nanorods blended organic solar cells. This work would lead in the emergence of future plasmon based efficient organic electronic devices.« less
