However, the [110] oriented SiCNWs could be interesting for appliions in microelectronics due to its peculiar symmetry which is similar to a nanotube. This work studies the effects of hydrogen and Oxygen in the electronic band gap of Silicon Carbide Nanowires (SiCNW) grown in [110] direction by means of Density Functional Theory.
