By using Density Functional Theory, First Principle Calculation has been performed <br /> <br /> <br /> <br /> <br /> <br /> to investigate electronic and magnetic properties of Hydrogenated Germanene. <br /> <br /> <br /> <br /> <br /> <br /> As Silicene honeycomb structure, pristine Germanene also has three <br /> <br /> <br /> <br /> <br /> <br /> kinds of stable condition: planar, low buckling, and high buckling. Both planar <br /> <br /> <br /> <br /> <br /> <br /> and high buckling honeycomb structure have metallic properties, whereas low <br /> <br /> <br /> <br /> <br /> <br /> buckling is semi-metal with zero band gap. Compare to planar and high buckling, <br /> <br /> <br /> <br /> <br /> <br /> low bucking is the most stable structure. This result is comparable to other <br /> <br /> <br /> <br /> <br /> <br /> works. Low buckling has been performed with hydrogen atoms with several con- <br /> <br /> <br /> <br /> <br /> <br /> figurations. Chairlike Obtuse and Boatlike Obtuse configuration become the most <br /> <br /> <br /> <br /> <br /> <br /> stable configuration. Both of those configuration are semiconductor. Only for <br /> <br /> <br /> <br /> <br /> <br /> Chairlike Obtuse configuration, it has non zero magnetic moment. Comparing <br /> <br /> <br /> <br /> <br /> <br /> with 100 percent Hydrogenated Silicene and 100 percent Hydrogenated Graphene, <br /> <br /> <br /> <br /> <br /> <br /> 100 percent Hydrogenated Germanene has the smallest band gap energy.
