From: Face-centered cubic carbon as a fourth basic carbon allotrope with properties of intrinsic semiconductors and ultra-wide bandgap

Fig. 5

a Work function measured by Kelvin probe (KP) in darkness and under illumination at  λ= 172 nm. b Photoemission spectra PY(hν)1/3 measured by the photoelectron yield spectroscopy (PYS), in which the thin dashed lines represent the linear fits for the determination of the ionization energy. c Experimentally established electronic density of states (DOS) spectra that were acquired from PYS measurements (the energy of the valence band maximum (VBM) is set to 0 eV).
