Hello Serifi,

as far as I can imagine you ant to calculate more semi conductors because the phonons in metals are (more or less) unsignificant for thermal transport.

I would suggest to have a look at (theory) the book of J.M. Ziman: "Elektrons and Phonons", (application) D.M. Rewe: "Thermoelectrics Handbook" -- just for the fun of it I like to cite C. Herring "Transport Properties of a Many-Vally Semiconductor"BellSysTechJour, p.237(1955) -- "... And if the crystal is strained any or all of these parameters may change ..." :-)

Regards

Ernst

Thanks you Professor Riaz and Dr Ernst

For the thermal conductivity i want to investigate it because it's directly related to the electron-phonon coupling strength i will not search in the contribution of each phonon mode in the thermal conductivity, and obviously the conductivity change in case when the strain is applied.

i find a code namely alamode wish that can be easy to proceed with :)

best
