the transmission spectra, density of states and current-voltage characteristics shows that the defect effect on the electron transport is considerably varied depending on the positions and the orientations.... The transport properties of the defective structure greatly depend on both of bandgap narrowing and carrier backscattering. As shown in Figure 6, in spite of decreasing the backscattering, electrical current......
