TLDR
In this paper, the lattice dynamics of 12 chalcopyrite type compounds were investigated based on a rigid ion model and the calculated force constants, normal co-ordinates and potential energy distributions were compiled and discussed.Abstract:
The lattice dynamics of 12 chalcopyrite type compounds CuAlS 2 , CuGaS 2 , CuInS 2 , AgGaS 2 , AgGaSe 2 , AgInSe 2 , ZnSiP 2 , ZnGeP 2 , CdSiP 2 , CdGeP 2 , CdSnP 2 , and CdGeAs 2 have been investigated based on a rigid ion model. As the anisotropy of the dynamic charges is not very pronounced the calculations were done assuming isotropic charges. The calculated force constants, normal co-ordinates and potential energy distributions are compiled and discussed.read more

Lattice dynamics and related properties of AIBIII and AIIBIV compounds, I. Elastic constants
TL;DR: The present state of knowledge of the elastic properties of the ternary chalcopyrite compounds and some related materials is reviewed in this paper, where results of experimental elastic constant determinations are critically evaluated by comparing with other experimentally available material parameters that directly depend on the elastic constants.

Influence of the GA Content on the Mo/Cu(In,Ga)Se2 Interface Formation
TL;DR: In this paper, a linear increase of the frequency of the chalcopyrite A1 mode with increasing Ga content was observed and a reduced formation of MoSe2 at the Mo/CIGS interface for higher Ga contents.
