Born effective charges drift removed

WebMar 7, 2011 · Abstract. We performed first principles LAPW linear response calculations for KNbO 3 in the cubic, experimental tetragonal, and theoretical ground state rhombohedral structures. We found that the Born effective charges and dielectric constants strongly depend on the small atomic displacements involved in the ferroelectric phase transitions. http://www.wien2k.at/reg_user/textbooks/WIEN2k_lecture-notes_2013/BerryPI-tutorial-2-Born%20effective%20charges%20in%20GaAs.pdf
