    Survey Responses: Mail Versus Email Solicitations

    Get PDF
    Surveys, particularly electronic surveys, are becoming popular methods of eliciting consumer responses. For example, many businesses now have survey sites printed on the bottom of receipts with some future discount as an enticement to participate. Clearly, the intent of such incentives is to stimulate participation. Surveys have also become popular in academia, but rarely are incentives offered. Clearly, those in academia also prefer a high participation rate, but without financial incentives what can be done to encourage participation? This research attempts to address that question

    Supercell technique for total-energy calculations of finite charged and polar systems

    We study the behavior of total-energy supercell calculations for dipolar molecules and charged clusters. Using a cutoff Coulomb interaction within the framework of a plane-wave basis set formalism, with all other aspects of the method (pseudopotentials, basis set, exchange-correlation functional) unchanged, we are able to assess directly the interaction effects present in the supercell technique. We find that the supercell method gives structures and energies in almost total agreement with the results of calculations for finite systems, even for molecules with large dipole moments. We also show that the performance of finite-grid calculations can be improved by allowing a degree of aliasing in the Hartree energy, and by using a reciprocal space definition of the cutoff Coulomb interaction

    Electron localization : band-by-band decomposition, and application to oxides

    Full text link
    Using a plane wave pseudopotential approach to density functional theory we investigate the electron localization length in various oxides. For this purpose, we first set up a theory of the band-by-band decomposition of this quantity, more complex than the decomposition of the spontaneous polarization (a related concept), because of the interband coupling. We show its interpretation in terms of Wannier functions and clarify the effect of the pseudopotential approximation. We treat the case of different oxides: BaO, α\alpha-PbO, BaTiO3_3 and PbTiO3_3. We also investigate the variation of the localization tensor during the ferroelectric phase transitions of BaTiO3_3 as well as its relationship with the Born effective charges

    Optical properties of the vibrations in charged C60_{60} molecules

    Full text link
    The transition strengths for the four infrared-active vibrations of charged C60_{60} molecules are evaluated in self-consistent density functional theory using the local density approximation. The oscillator strengths for the second and fourth modes are strongly enhanced relative to the neutral C60_{60} molecule, in good agreement with the experimental observation of ``giant resonances'' for those two modes. Previous theory, based on a ``charged phonon'' model, predicted a quadratic dependence of the oscillator strength on doping, but this is not borne out in our calculations.Comment: 10 pages, RevTeX3.
