題名: | Doping a C60 molecule with potassium atoms: A theoretical study | 作者: | 楊志開 Yang,Chih-Kai |

Ab initio calculations based on density functional theory indicate that K atoms are fairly strongly bound to the carbon cage. The electrical conduction of the structure is also enhanced after each successive doping of K. We also observe a downward shift of energy levels toward the Fermi energy with the increase of doping. These properties are very consistent with experimental results. The K-doped structure is promising for applications in molecular electronics. | 關聯: | Journal of Applied Physics,98,116103-1-116103-3 | 資料類型: | article |
