摘要
Formation of the homologous series of layered compounds nBi(2) . mBi(2)Te(3) and nGeTe . mBi(2)Te(3) is analyzed. For both series, the crystal structure contains two-layer (Bi-2 or GeTe) and five-layer (Bi2Te3) packets perpendicular to the c axis. Unlike the Bi-2 packers, the GeTe packets do not retain their individually during crystal structure formation; they are linked to the Bi2Te3 five-layer packets to form new multilayer packets leading to a considerable change in the character of interatomic interactions.
