Hello,

Could you point out a good article(s) covering Perovskite crystal structures? There's plenty of literature out there covering perovskite structures, mostly properties or applications of individual crystals. Googling results are either very specific or too general or complete textbooks.

If you've worked on perovskites before, or are familiar with it, is there a good review article covering the basics and why these structures are so popular and the subject of so much research?

I'm doing an Electrical engineering graduate class review of perovskites, focusing on the transverse optical modes and would like to cover a few well cited /classic papers to give everyone a background on these crystals in general, and suggest materials for further reading if students are interested.

I'm at a University, so I do have access to published papers. My usual process of tracking down the more popular papers through references seem to have taken me nowhere so far.

Thank you very much.

Well if you look at the wikipedia article, it talks about a number of interesting functional properties that perovskites can display. It also talks about how the size requirements for stability of the cubic structure are stringent. I only know a limited amount about the specific case of tetragonal perovskite ferroelectrics. But it seems like those stability requirements are probably related to all (or most of)these functional properties you can observe. So I would suggest picking a few of those and seeing how the perovskite structure influences that particular property.
 
I don't know exactly what you're looking for but a lot of the transition metal oxides have a perovskite (either perfect but could be severely distorted) structure. Transition metal oxides are interesting today but many exotic properties such as high-Tc superconductivity, CMR (colossal magnetoresistance), ferroelectricity, etc. are exhibited by these materials.

There's a good review by Imada in the Review of Modern Physics (circa 1998) entitled "Metal-insulator transition", i.e. google "metal-insulator transition imada" and it's the first link.

You mentioned optical transverse modes so I'm assuming that these are phonon modes. So maybe include "phonon modes transition metal oxides" in a search as well.

Hope this helps!
 
From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
Hi. I have got question as in title. How can idea of instantaneous dipole moment for atoms like, for example hydrogen be consistent with idea of orbitals? At my level of knowledge London dispersion forces are derived taking into account Bohr model of atom. But we know today that this model is not correct. If it would be correct I understand that at each time electron is at some point at radius at some angle and there is dipole moment at this time from nucleus to electron at orbit. But how...
