Abstract

We have studied the electronic structure and magnetic properties of Nitrogen and Carbon codopedZnO(5,0) single-walled zigzag nanotube using first-principle calculations based on the density functional theory. We performed our calculations forN- andC- codopingZnOnanotube in two different configurations. For the first configuration in which the two impurity atoms (NorC) are on first nearest-neighbor sites in the plane of codoping, our calculation predicts that theN- andC-codopedZnOnanotubes are antiferromagnetic material with no net magnetization. On the other hand, it is found that for the configuration in which the two impurity atoms are next nearest-neighbors, a spin polarization results in a magnetic moment in theN- andC-codopedZnOnanotubes.
