比如 想要知道 Silver (111) 的表面密度是 n*10E+15/cm2 ?
多谢啦 |

states? or some other excitations? |

发帖数: 1279 | 4 you can calculate it yourself quite easily. silver is an fcc crystal, with a
= 4.086 Angstroems
the section of a (111) plane that's within the cubic unit cell is a
equilateral triangle with side length a*sqrt(2). And the number of atoms
lying in this triangle is 2 (I believe, you could check). then you can
calculate the atom number density |
