Thus , we can restrict the force constants to few near neighbors . In practice , one
may have to include the effect of several neighbors because the elastic
disturbances in the matrix may extend quite far . However , the number of
neighbors to be ...

Equating the coefficients of k ; ? in the corresponding elements of the matrices D (
k ) and A ( k ) , we get the following relations between the force constants and the
elastic constants A + 2D = ( 11 B + 2D = 266 E = C44 F + 2G = C44 ( 50 ) H ...

First , let us note that the matrix DP is exactly similar to the dynamical matrix of a
two - dimensional square lattice of lattice constant equal to a with nearest and
next nearest neighbor interactions given by the following force constant matrices
...
