Gap direct.

Similarly, for 18 different samples of TiO 2 the direct/optical/indirect band gap estimates are 3.5/3.3/3.0 eV, whereas the theoretical values are 3.2 eV for both direct and indirect band gaps. Thus it appears that the direct band gap Tauc formula α E 2 overestimates the band gap, and indirect Tauc formula α E 1 / 2 provide a number even …Direct bandgap semiconductors A common and simple method for determining whether a band gap is direct or indirect uses absorption spectroscopy . By plotting certain powers of the absorption coefficient against photon energy, one can normally tell both what value the band gap has, and whether or not it is direct. α2Grasping for things to do during a gap year after high school?
