a Relative change of the band-edge energy (black) and electron-hole overlap (blue) as a function of the applied electric field. b (resp c, d) Energy profile (black) as a well as electron (ψe, blue) and hole (ψh, red) wavefunctions under an electric field (F) of 12 kV cm−1, (resp 1300 kV cm−1 and 7000 kV cm−1). The vacuum energy is set to 0 eV. The wavefunctions are shifted to their eigen energy.
