Berry Phase (two dimensional system) Date: 2023/05/09 18:14 Name: ghina Hi All. I need assistance for calculating the in-plane polarization in two dimensional system. The guidebook only provide an example and explanation for the bulk system with the Polarization unit in muC/cm^2. I would like to have an output for the polarization value in pC/m (because it is two dimensional). Is there anyway to obtain this? Regards, Ghina

Re: Berry Phase (two dimensional system) ( No.1 ) Date: 2023/05/10 01:53 Name: Naoya Yamaguchi Hi, You can convert the 3D polarization value to the 2D one by multiplying the 3D value by the length of the out-of-plane lattice constant.
