High-resolution angle-resolved photoemission investigation of the quasiparticle scattering processes in a model Fermi liquid: 1T-TiTe2

We present a combined angle-resolved photoemission spectroscopy and resistivity study of the model Fermi liquid system 1T-TiTe2. From the analysis of the quasiparticle spectral line shape we identify and separately evaluate the electron-electron. electron-phonon, and impurity scattering contributions to the quasiparticle lifetime. There is a clear correspondence between spectroscopic and transport data. A residual low-temperature spectral linewidth (Gamma (o)=17 meV) indicates that the three-dimensional nature of the electronic states cannot be neglected even in this quasi-two-dimensional material.
