Zone-Folded Phonons and the Commensurate-Incommensurate Charge-Density-Wave Transition in 1T-TaSe2 Thin Films.
Bulk 1T-TaSe2 exhibits unusually high charge density wave (CDW) transition temperatures of 600 and 473 K below which the material exists in the incommensurate (I-CDW) and the commensurate (C-CDW) charge-density-wave phases, respectively. The (13)(1/2) × (13)(1/2) C-CDW reconstruction of the lattice coincides with new Raman peaks resulting from zone-folding of phonon modes from middle regions of...
متن کاملSTM studies of TbTe3: evidence for a fully incommensurate charge density wave.
We observe unidirectional charge density wave (CDW) ordering on the quasi-2D material TbTe3 with a scanning tunneling microscope at approximately 6 K. Our analysis indicates that the CDW is fully incommensurate, with wave vector qCDW approximately 0.71x2pi/c. By imaging at various tip-sample voltages, we highlight effects of the subsurface layer and its effect on the CDW. We also observe an add...
متن کاملAlternative route to charge density wave formation in multiband systems.
Charge and spin density waves, periodic modulations of the electron, and magnetization densities, respectively, are among the most abundant and nontrivial low-temperature ordered phases in condensed matter. The ordering direction is widely believed to result from the Fermi surface topology. However, several recent studies indicate that this common view needs to be supplemented. Here, we show ho...
متن کاملMultiple Fano effect in charge density wave systems
A general framework for analyzing the multiple Fano effect (MFE) in charge density wave (CDW) systems is developed. The MFE occurs when IR active modes have frequencies above the CDW gap and interference between the IR modes and the electronic continuum leads to a series of resonances and anti-resonances. We parameterize the peaks and dips of the absorption by a set of bare frequencies, a pinni...
