(a) The δ E (the energy seperation between band α and band ω at γ as defined in Figs. 10(d) and 11(c) ) as a function of lattice constant. (b) The effective mass m * of band α as a function of lattice constant, where m _e is the mass of free electron. (c)–(d) Comparison of DFT calculation and experimental band dispersion around zone center of FeSe^BU and FeSe^SX, respectively. Panels (a)–(d) are reprinted with permission from Ref.
