ABSTRACT<\/strong><\/p>\n\n\n\n The structural stability, adsorption energy and electronic property characteristics of \u00a0<\/strong>and <\/strong>\u00a0gases on neutral nine-atom germanium-phenyl[Ge9<\/sub>(C6<\/sub>H5<\/sub>)] nanocluster were studied using DFT at CAM-B3LYP method and Lanl2dz basis set. These molecular gases adsorption on neutral nine-atom germanium-phenyl nanocluster were optimized at B3LYP\/Lanl2dz basis set. The structural stability of molecular gas adsorptions on [Ge9<\/sub>(C6<\/sub>H5<\/sub>)] nanocluster were discussed in terms of\u00a0 calculated energy and dipole moment. The adsorption of \u00a0<\/strong>and \u00a0<\/strong>molecules on [Ge9<\/sub>(C6<\/sub>H5<\/sub>)] nanocluster was studied using the above method and\u00a0 basis set. A number of possible different relative orientations of the gas interactions with the neutral nine-atom germanium-phenyl nanocluster were investigated. The adsorption energy of the stable structure , and were calculated to be -14.75, -17.52 and -19.32 eV respectively. This results suggest that the interaction between the molecular gases on [Ge9<\/sub>(C6<\/sub>H5<\/sub>)] nanostructure surface are strong.\u00a0 Also, the electronic properties of the molecular gases on neutral nine-atom germanium-phenyl[Ge9<\/sub>(C6<\/sub>H5<\/sub>)] nanocluster was found to be affected by the adsorption of \u00a0<\/strong>and \u00a0<\/strong>gas . The density of state showed a decrease in the HOMO-LUMO band gap energy change \u00a0of the nanostructure upon the adsorption of\u00a0 \u00a0<\/strong>and \u00a0<\/strong>gasmolecules. Considering these changes in the HOMO-LUMO band gap energy that was calculated to occur during \u00a0<\/strong>and \u00a0<\/strong>adsorption, it is clear that [Ge9<\/sub>(C6<\/sub>H5<\/sub>)] nanocluster is sensitive to and \u00a0<\/strong>adsorption suggesting that [Ge9<\/sub>(C6<\/sub>H5<\/sub>)] nanocluster has potential to act as sensor.<\/p>\n\n\n\n Keywords<\/strong>: Adsorption Energy, Sensor, First Principle Calculation, HOMO-LUMO, Nanostructure, Band gap, Germanium-\u00a0phenyl.<\/em><\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" ABSTRACT The structural stability, adsorption energy and electronic property characteristics of \u00a0and \u00a0gases on neutral nine-atom germanium-phenyl[Ge9(C6H5)] nanocluster were studied using DFT at CAM-B3LYP method and Lanl2dz basis set.
