Fig. 3: Plasmon behavior for α-Ti2O3.
From: Ultra-flat and long-lived plasmons in a strongly correlated oxide
a, b Calculated EELS with LFE for α-Ti2O3 along Γ-S0 and Γ-T directions, respectively. White circles outline the plasmon branches extracted from EELS and the size represents the intensity of plasmon modes. c, d Dielectric function (upper panel) and loss function (lower panel) of α-Ti2O3 for q = 0.077 Å−1 and q = 0.77 Å−1 along the Γ-S0 direction, respectively. e, f Dielectric function (upper panel) and loss function (lower panel) of α-Ti2O3 for q = 0.044 Å−1 and q = 0.44 Å−1 along the Γ-T direction, respectively. The data indicated by the solid (dashed) lines are results with (without) the LFE. The circles denote the zeros of Reε(q,ω). Source data are provided as a Source Data file.
