Electronic properties of boron nano-ribbons: - DFT study

Electronic properties of boron nano-ribbons have been studied using density functional techniques employing ultra-soft pseudo-potentials. Spin restricted calculations were performed for boron nano-ribbons constructed from stable boron sheet$^{1}$ structures. Different stable edge configurations of nano-ribbons were observed. Band structure analysis was performed and Density of states was calculated to determine the electronic phase of these nano-ribbons. Comparisons with the carbon systems will be made.
