(a) The schematic diagram of the orbital evolution at the Γ point for Pb-H. The stage (I) and (II) represent the effect of chemical bonding and spin-orbital coupling. The blue dot-dash line represents the Fermi level. (b,c). Evolution of s and px,y orbitals at Γ point under hydrostatic strains of Pb-H and Pb-SiH3 respectively. The dashed line represented the Fermi level and light blue shaded area highlights the topologically trivial region.
