摘要：
The electronic properties of a recently proposed new structure, twinning superlattice, based on the periodic array of twin boundaries in Si and Ge, are calculated. In addition to showing miniband structure as conventional superlattices do, the twinning superlattices exhibit some unusual electronic properties, such as zero energy gaps, interface state derived minibands, and indirect miniband gaps.
