12. Figure 3 of Zou et al. [3] showed two different onset near 4.3 and 2.6 eV in the opical absorption for undoped InTaO4 However they did not point out the onset at 4.3eV in their paper Thus, although Zou et al assigned the band gap (VB to CB) to the 2.6 eV onset contraty to the assignment of Matsushima et al. their optical absoption data is consistent with the observation reported by Matsushima et al
