In a semi-conductor (silicon), the electron wave function is obtained from localized molecular orbitals. These orbitals are built from hybridized atomic orbitals (sp in silicon). If we neglect the interactions between the orbitals which do not point at one another, we obtain only two values for e. These values are infinitely degenerate. The interactions between the orbitals give a spliting of the degenerate levels in two bands. 

LaTer-LaSbj system. A large solid solution exists from LaTe2 to the composition limit LaSbi sTeos, in which the substitution of Te by Sb creates an orthorhombic distortion of the tetragonal structure of LaTc2 (Wang et al., 1967). This substitution decreases the resistivity, and degenerate p-type semi-conductors are obtained. The thermoelectric power first increases then decreases as the material becomes more metallic (Narasimhan et al., 1968).
