The electronic structure of ZnO is calculated by using an accurate full-potential linear plane-wave based on the density function theory and WIN2K package. The curves of energy band and density of states of ZnO are gained. The energy gap is 0.9eV that is better some of the computed results by theory approaches and smaller than the experimental value obtained by X spectra. After analyzing it is known that the coulomb repulsion between 3d state of Zn and 2p state of O is very strong leading to the increase in the energy of O2p and the energy gap become smaller.

In this article, we have reproduced the tight-binding π band dispersion of graphene including up to third nearest-neighbors and also calculated the density of states of π band within the same model. The aim was to find out a set of parameters descending in order as distance towards third nearest-neighbor increases compared to that of first and second nearest-neighbors with respect to an atom at the origin. Here we have discussed two such sets of parameters by comparing the results with first principle band structure calculation.1

Using symmetry adapted basis sets of linearly combined Bloch sums, we summarize the basic equations for one-dimensional energy band structure calculations of extended-Hückel type such as SCC (Self-Consistence of Charge) and SCCC (Self-Consistence of Charge and Configuration). In addition to the considerable computational savings achievable by this technique, its main advantage is that band indexing difficulties can be systematically excluded. Furthermore, it turns out that backtransformations into the original atomic orbital basis are unnecessary throughout. As an illustrative example, we document the energy band structure of a one-dimensional model geometry of highly conducting bis(2,5-dimethyl-N,N′-dicyanoquinonediimine)copper(I) (2,5-DM-DCNQI)2Cu. In spite of its one-electron nature, the outlined energy band structure calculation method appears to be useful to rationalize the unusual electronic properties of this “organic metal”.
