摘要：

We have studied the electronic properties of pristine zigzag germanene nanoribbons (ZGeNRs) using ab initio method. The effect of boron and nitrogen doping on electronic properties of ZGeNRs at two different edge sites is also calculated. It is observed that the H-terminated pristine ZGeNRs exhibit semi-metallic behavior while the ZGeNRs doped with boron and nitrogen shows the metallic behavior. The electron density calculation shows that the density is low in pristine ZGeNRs while it is high in the doped ZGeNRs. The transmission coefficient analysis also suggests the same. As the transmission is sensitive to doping, hence, ZGeNRs have potential application in nanoelectronics devices.
