Surface-state evolution and constant-energy contours. Surface states on the (101) and (111) surfaces at three representative pressures. The three columns from left to right correspond to the 0, 16, and 26 GPa systems, respectively. The upper panels (a)-(c) show the results for the (101) surface, while the lower panels (d)-(f) show those for the (111) surface. The insets show constant-energy contours at selected energies.
