Amplitude mode of charge density wave in TTF [ Ni ( dmit ) 2 ] 2 observed by electronic Raman scattering

We measured the optical signature of charge density waves (CDWs) in the multiband conductor TTF [ Ni(dmit)2]2 by electronic Raman scattering. At low energies, a hump develops below 60 K. This hump is associated to the amplitude mode of the CDW with an energy around 9 meV. Raman symmetry-resolved mea...
