Figure 4
(a1-a3) Second E derivative of the E-k images for x = 0.24 taken at 130 K, 70 K and 10 K, respectively. Green curves are the guides to the eyes. (b) T dependence of the second E derivative EDCs of twinned samples of x = 0.24 taken at the momentum indicated by the broken lines in (a1-a3). Black open circles represent the spectral dips corresponding to the energy position of δ hole bands. (c1-c3) The same as (a1-a3) but for x = 0.30. (d) The same as (b) but for x = 0.30. (e1–e3) The same as (a1–a3) but for x = 0.45. (f) The same as (b) but for x = 0.45. (g1–g3) The same as (a1-a3) but for x = 0.61. (h), The same as (b) but for x = 0.61. (i1-i3) The same as (a1-a3) but for x = 0.74. (j) The same as (b) but for x = 0.74. (k1–k3) The same as (a1-a3) but for x = 0.87. (l) The same as (b) but for x = 0.87.
