2O gap (0.99 vs 2.17 eV), and hybrid functionals overestimate the CuO gap (2.74 vs 1.57 eV direct) [16]. A recent GW study demonstrated that the band gap energy and density of states (DOS) in CuO strongly depend on rather subtle details of the calculations [21]. The current knowledge about the electronic structure of Cu 4O 3 is even more limited.In a direct band gap semiconductor, the top of the valence band and the bottom of the conduction band occur at the same value of momentum, as in the schematic below.

The influence of size on band gap was explored, and the results suggest that for semiconductors with narrow and moderate band gaps, the band gap increases as the size decreases. When the size of the particle decreases, the spaces between the bands get wider due to the lattice parameters rise as the diameter gets smaller.
