I am good at DOS, Band structure and phonon studies. I would like to extend my studies to Dielectric and Ferroelectric studies. How to find the polarization in the material?
You can find out polarization of the material from dielectric studies. In dielectric study, draw the graph between dielectric constant and log f. In the graph, if the dielectric constant goes on decreasing with respect to the frequency then space charge polarization taking place. Once the space charge polarization is over the dielectric constant almost remains constant for the remaining frequency range.
hi, can you give me a detail for calculation a phonons properties
For Ferroelectric studies. and How you can find the spin polarization in the material, see our privious works attached bellow
Dear Yousif Shoaib Mohammed. I have gone through the attached files you recommend but still I need your kind support. I am working on Multiferroic materials (BiFeO3) using Quantum Espresso but i failed to calculate the polarization of the material, thanks.
