Journal reference: Comput. Phys. Commun. 24(1981)181
Programming language: Fortran.
Computer: CDC-3600.
Operating system: SCOPE 6.3.
RAM: 35K words
Word size: 48
Keywords: K-space, Energy bands, Solid state physics, Band structure.
Classification: 7.3.

Nature of problem:
This work is concerned with the band structure calculations of cubic semiconductors.

Solution method:
We applied Brust's modification of Lowdin's perturbation technique for the energy band calculations of the cubic semiconductors. With this technique the band structure calculation problem reduces to the eigenvalue problem of the truncated complex symmetrical matrix.

Restrictions:
Only for cubic semiconductors.

Running time:
For two points in k-space this program needs about 3 min.
