Charge-density-wave in 1T-TiSe2: exciton-phonon separation by femtosecond valence band dynamics
We investigate the driving mechanism leading to charge-density-wave transition in 1T-TiSe2 single crystals. Our results show that both exciton instability and phonons cooperate to develop the charge ordered phase below 202 K.
