I want to calculate the CBM and VBM from the band gap of ZnO. But is unable find out the absolute electronegativity of ZnO. Please help me with proper references.
Martin Allen and coauthors have determined the (surface orientation dependent) work function to lie between 4.5 and 4.7 eV. The attached paper also contains references to work by others with similar results. The absolute electronegativity (or electron affinity) is surface-independent, but its exact determination is difficult due to the spontaneous polarization along the c-axis in ZnO.

this paper showed the electronegativity of ZnO, but I also want to know how I can calculate the electronegativity of semiconductors.
