Figure 3: Temperature dependence of the band structure.

From: Charge density wave transition in single-layer titanium diselenide

Figure 3

(a) ARPES spectra around the zone centre reveal that the valence band top shifts towards the Fermi level when the temperature is increased from 10 to 300 K. (b) ARPES spectra around the zone boundary . Emergence of the back-folded valence bands at low temperature indicates formation of the (2 × 2) CDW phase. All data were taken with 58 eV photons.
