Talk:Superlattice

Equilibrium/artificial
There is a bit of ambiguity whether superlattice refers to equilibrium crystal structures (such as the NaCl-structure, which is a superlattice of the simple cubic structure), or artificial periodic layers. To me as a condensed matter physicist the first meaning is primary, while I do see that for, e.g., the semiconductor community this is different. As it is, all paragraphs apart from the Discovery understand the second meaning. I think that at least for the introduction the ambiguity should be clarified, and it would be nice if also the following paragraphs clearly state which of those two aspects the discuss. Common to both aspects is that if you keep the positions of all atoms fixed but randomly exchange the elements, you get some underlying fundamental lattice, while if you consider also the occupations of the atomic sites, you have a longer repeating distance. This should go into the introduction. Of course, with artificial superlattices you have also lattice constant differences (not to speak of arrays of quantum dots), so it seems that the first meaning is the only valid one in the strict sense of the word.

Superstructure article
Superstructure Doesn't it worth to make a common article for this kind of structures? There is also a relationship with articles where multilayer optical devices are mentioned.--193.146.9.175 (talk) 11:04, 19 May 2016 (UTC)
