Abstract: The energy band structure of TiN/VN superlattice thin film is calculated using the pseudopotential method.The total energy of the TiN/VN superlattice cell is also calculated.Then the relationship between C44 and the period of superlattice λ is obtained.The superlattic period where C44 reaches the maximum basically accords with the experimental data.

Key words: superlattice, pseudopotential, shear elastic module C44
