Dear Chandan Biswas,

Thank you very much for the reference.

Best regards,

Hi, P. Grima Gallardo,

I have found a 2006 structural study written by Schorr and Geandier which deals with the temperature-depedency of CuInSe2. Perhaps it is of interest, even though it does not include Raman measurements:

http://onlinelibrary.wiley.com/doi/10.1002/crat.200510604/abstract

There are many references including CuInSe2 structures, but none that report as many different crystal structures as this Schorr and Geandier one. I hope it helps.

regards,

Daniel

Dear Daniel Lundberg,

Thank you very much for this interesting reference.

I am working on the p-T phase diagram of CuInSe2 and have curiosity why the order-disorder transition has never reported in applied pressure measurements where authors report a direct transition from ordered chacopyrite to cubic NaCl-like structure. I think that something is missed.

Best regards,

Pedro

Dear Dr. Gallardo,

Its my pleasure. There are not much temperature dependent Raman study on CuInS2. I was lucky to get this one for you. Hope this will be helpful to you.

With best,

Chandan
