(a) TARPES spectra of BP along c-axis (Upper panels) recorded at a various pump-probe delay times and its difference to the image before pumped (Lower panels). (b) Ultrafast time evolution of conduction band population in frames A–D. The frames A to D represent integrated transient photoemission intensity in the angular range of (±8) degree and energy region of [0.44, 0.50], [0.38, 0.44], [0.32, 0.38], [0.26, 0.32] (units of eV), respectively.
