Extended Data Fig. 2: Time-resolved ARPES spectra over a wide energy range with different temperatures.
From: Spin-polarized spatially indirect excitons in a topological insulator
a, Non-equilibrium ARPES spectrum of energy versus momentum cuts along the \(\bar{\Gamma }-\bar{{\rm{M}}}\) direction, measured at 20 K before and 1, 2.5, 5, 10, 20, 30 ps after pumping from left to right. The white dashed-line represent the Fermi level. b, The same as panel a, but measured at 180 K.
