Fermi Velocity and Effective Mass Variations in ZGaN Ribbons: Influence of Li-Passivation

The paper presents the structural stability and electronic properties of Zigzag Gallium Nitride nano ribbons(ZGaNNR) by considering the lithium(Li) atom by employing density functional theory (DFT). Li atom has been considered as a passivating element at various symmetric sites. By using Li atoms, a...
