In this study, the level statistics of the three-dimensional tight-binding model with non-Hermitian disorder, introduced by Tzortzakakis, Makris, and Economou (TME), and its variants were analyzed. The shift-and-invert Arnoldi method was used to analyze the eigenvalues of the TME model up to acubic lattice, which was larger than those used in previous studies. The results showed that the magnitude of critical disorders in the isotropic TME model was larger than that reported in previous numerical studies for smaller systems. The localization-delocalization transition in an anisotropic model was also investigated. The computational method adopted in this study was shown to be quite effective for large-scale analysis of the calculation of all eigenvalues of sparse non-Hermitian matrices.
