We have studied the pressure-induced neutral-ionic phase transition of tetrathiafulvalene-chloranil (TTF-CA) with polarized infrared absorption spectra of single crystals inside a diamond anvil cell (DAC). The evolution of the phase transition is complex, implying at least two steps. The nature of the intermediate regime is briefly discussed.

Abstract
We have studied the pressure-induced neutral-ionic phase transition of tetrathiafulvalene-chloranil (TTF-CA) with polarized infrared absorption spectra of single crystals inside a diamond anvil cell (DAC). The evolution of the phase transition is complex, implying at least two steps. The nature of the intermediate regime is briefly discussed.File in questo prodotto:
