finit electric field calculation, polarization
Now, I am carring out a finit electric fields calculation for PTO. When electric fields is increased, the poplarization is changed to negative. Through see the tutorial, I find that P=\chi*E+\chi(2)*E^2. Now ,I want to ask that , /chi or /chi(2) may be detemined by DTPT or other method? How to get t...
