Table 1. The different CDW phase in 1T-TaS₂ and their manifestation in terms of the CDW orientation angle Φ (the angle between the CDW unit cell and that of the unreconstructed atomic lattice) and CDW amplitude.

The values of transition temperature and angle associated with different CDW phases under the thermodynamic conditions (cooling and warming) are taken from (7, 35). The values of the transition optical dose and the normalized CDW intensity Î_CDW are extracted from the metastable phases obtained at +20 ps in the optically induced phase transitions characterized by femtosecond electron crystallography.
