Using quantum theory (QT) combined with Tight-binding Approximation (TBA), we studied the electronic properties for single-orbital one dimensional, two-dimensional and diatomic crystalline chain to get simply qualitative understanding of electronic structure calculation in the periodic systems. Density of states (DOS) is one of the electrical properties that we try to understand within the band structures that lead to be able to know the mechanism of transport in the materials. The band structure and density of state (DOS) for both cases were calculated by using FORTRAN code. The calculation of DOS for ordered and disordered systems were performed via a numerical decimation method.
