(a) Band separation and (b) critical temperature of the nematic transition. (c) In-plane lattice constant of FeSe derived from the inversion of Brillouin zone size as a function of FeSe thickness. (d) Phase diagram of FeSe combining the parameters in panels (a)–(c) and the bulk FeSe phase diagram under hydrostatic pressure. Panels (a)–(d) are reprinted with permission from Ref.
