General Questions and Answers / kappa in complex band structure

« on: January 2, 2019, 15:22 »

Could you please let me know how the "kappa" axis is  generated from the reciprocal cartesian coordinates in complex band structure. In the online documentation. `the complex k is multiplied with (L/pi where L=a/2) in 3D visualisation but not in case of 2D visualistaion  Why is it so?I However, the reference journal in the documentation shows that both imaginary and real k are in terms of (2pi/a). I am extracting the complex band structure data to use for fitting with some analytical CBS dispersion.  How should I project the imaginary k from my analytical calculations to fit with  CBS extracted from ATK. I ask this as I am a bit confused about the multiplication factor (L/pi).
