There is a lack of consistency in the literature values of the band gaps of TiO 2’s polymorphs as shown in Table 1. TiO 2 is usually assumed to be a direct band gap semiconductor, so many labs measure for the direct band gap (labeled D). The direct gap transitions are fitted with an exponentially modified Gauss function, whereas the indirect gap contribution is fit with a simple Gaussian. A weak high-energy peak corresponding to direct-gap emission from the Ge buffer layer is also fit with a Gaussian. FIG. 2.Not a job for everyone.

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.
