Ferroelectrics Optical susceptibility Ab initio methods Link to publisher's homepage at http://ijneam.unimap.edu.my/ We present a first principles calculations of the second-order optical response functions as well as the dielectrics function for ABO3 (A=K, Li, Ba; B=Ti, Ta, Nb) and A5B6C7 (A=Sb; B=S, Se; C=I, Br) ferroelectrics. Specially, we evaluate the dielectrics function ε(ω) = ε1(ω) - i ε2 (ω) and the second harmonic generation response coefficent χ(2) (-2ω, ω, ω, ω) over a large frequency range. The electronic linear electro-optic susceptibility χ(2) (-2ω, ω, ω, ω, 0) is also evaluated below band gap. These results are based on the series of self-consistent LDA calculations within DFT. 2016-03-28T08:18:57Z 2016-03-28T08:18:57Z 2010 Article International Journal of Nanoelectronics and Materials, vol.3 (2), 2010, pages 53-67 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41210 en Universiti Malaysia Perlis
