Fig. 5: The superiority of the plasmons in α-Ti2O3.
From: Ultra-flat and long-lived plasmons in a strongly correlated oxide
Comparison with other materials18,50,51,52,53,54,55,56,57 that have a relatively flat plasmon modes (Δωp < 0.1 eV). The length of the bar represents the start/end momentum of the flat plasmons. The width of the bar represents the flatness of the plasmon mode Δωp. Words using red, blue and black colors represent the three-dimensional, two-dimensional (monolayer or double layers) and bulk layered materials, respectively.
