A study on the morphology and stability of incommensurately modulated structures; a case study of ((CH 3) 4N) 2ZnCl 4− x Br x and AuTe 2

In this paper we investigate the stability of crystal forms of modulated structures. First, in a classical analytical approach the forms on AuTe 2 are investigated. Of the experimentally observed forms almost all important forms can be characterized as being stable. Secondly the forms on ((CH 3) 4N)...

Summary:In this paper we investigate the stability of crystal forms of modulated structures. First, in a classical analytical approach the forms on AuTe 2 are investigated. Of the experimentally observed forms almost all important forms can be characterized as being stable. Secondly the forms on ((CH 3) 4N) 2ZnCl 4− x Br x are investigated, using a simple Ising model and various parameters to determine the stability of forms. Here we find that satellite forms { hklm} are clearly less stable than the main forms { hkl0}.
