 The InSb semiconductor forms identical diamond structure as atomic number 32 with metal atoms occupying all of the A sites of the crystal and metallic element atoms occupying all of the B sites. A schematic illustration of the InSb structure is shown in Fig. 8.31(b). The electronic structure of InSb is extremely the same as that of atomic number 32. In every case, eight valence electrons area unit distributed among the four bonds. However, whereas the four negatron pairs occur midway between the atomic number 32 atoms within the atomic number 32 structure, the negatron pairs area unit drawn a lot of closely to the Sb atom within the InSb lattice. this could be explained with the thought of negativity employed in fashionable chemistry. The negativity of associate atomic species may be a live of the enticing power of the atom for associate negatron try. If 2 atoms, that area unit secure along, have identical negativity, the bonding electrons area unit shared equally between them. If, however, one atom is a lot of negative than the opposite, the negatron try is drawn a lot of closely to the atom that's a lot of negative and also the attractive force contains a polar character. a lot of charge is targeted close to the atom that is a lot of negative and also the alternative atom is a lot of electrically positive.
