Thermoelectric properties of Co-,Ir-, and Os-doped FeSi alloys: Evidence for strong electron-phonon coupling

Journal Article Sales, Brian C. ; Delaire, Olivier A. ; McGuire, Michael A. ; ... - Physical Review. B, Condensed Matter and Materials Physics

The effects of various transition-metal dopants on the electrical and thermal transport properties of Fe{sub 1-x}M{sub x}Si alloys (M = Co, Ir, Os) are reported. The maximum thermoelectric figure of merit ZT{sub max} is improved from 0.007 at 60 K for pure FeSi to ZT = 0.08 at 100 K for 4% Ir doping. A comparison of the thermal conductivity data among Os-, Ir-, and Co-doped alloys indicates strong electron-phonon coupling in this compound. Because of this interaction, the common approximation of dividing the total thermal conductivity into independent electronic and lattice components (K{sub total} = K{sub electronic} + K{submore »« less

Direct evidence of the importance of electron-phonon coupling in La/sub 2/CuO/sub 4/: photoinduced ir active vibrational modes. Technical report

Technical Report Kim, Y H ; Heeger, A J ; Acedo, L ; ...

We present direct evidence of the importance of the electron phonon interaction in pure La/sub 2/CuO/sub 4/. A number of photoinduced IR active vibrational modes(IRAV)and associated bleaching of the La/sub 2/CuO/sub 4/ phonon modes are observed in the spectral range below 700/cm. The observation of photoinduced IRAV implies the existence of structural deformation around the photoexcited carriers, indicative of coupling of the photoexcitations to the lattice. We find, in addition, evidence of a broad photoinduced absorption at higher energies suggesting an electronic transition deep within the energy gap.

The observation of photoinduced IRAV modes implies the existence of structural deformation around the photoexcited carriers, indicative of coupling of the photoexcitations to the lattice. In addition, a broad photoinduced absorption is found that peaks at about 0.5 eV, indicating an electronic transition deep within the energy gap.

Journal Article Kim, Y H ; Heeger, A J ; Acedo, L ; ... - Phys. Rev. B: Condens. Matter; (United States)

We present direct evidence of the importance of the electron-phonon interaction in pure La/sub 2/CuO/sub 4/. Photoinduced ir-active vibrational modes (IRAV) and associated bleaching of the La/sub 2/CuO/sub 4/ phonon modes are observed in the spectral range below 700 cm/sup -1/. The observation of photoinduced IRAV implies the existence of structural deformation around the photoexcited carriers, indicative of coupling of the photoexcitations to the lattice. We find, in addition, a broad photoinduced absorption which peaks at approx. =0.5 eV, indicating an electronic transition deep within the energy gap.
