(a) Projected band structure and (b) charge-density iso-surfaces of CBM and VBM states of CTF/As vdWhs. The blue and purple electronic states denote the contribution from the CTF and As layer, respectively. (c) Plane-averaged charge density difference and (d) electrostatic potential energy of CTF/As vdWhs along z-direction normal to the heterostructure. The inset in (c) is the 3D isosurface of the charge density difference.
