概要
- 論文の詳細を見る
The electronic band structure in the metallic copper is worked by the orthogonalized plane wave method in which the crystal potential is constructed by using both the Hartree's self-consistent field of Cu^+ ion cores with exchange and conduction electrons with the Slater's approximate exchange potential. The approximate energy versus k^^→ curve is obtained, which shows the strong resemblance to the free electron behaviour along three directions in k^^→ space, i.e., (1.0.0), (1.1.1)and(1.1.0). The results of the various methods of approximations performed so far are compared with ours together with some critical discussions.
