Phonons in Wurtzite (GaN) mu(AIN) nu Superlattices: Non-Monotoneous Dependence of the Number of Raman-Active Modes on Superlattice Period
Abstract
The symmetry of wurtzite (GaN)(sub m) (AlN)(sub n), is established to depend on the numbers of monolayers of constituent materials in the primitive cell being C?4 to 6V! (odd m+n) or C?1 to 3V! (even m+n). As a result it was shown that the number of Raman active modes depends non-monotonically on m+n.
