Fig. 5: Calculated Born effective charge (BEC) of atoms in CuSbSe2.
From: Structural and electronic features enabling delocalized charge-carriers in CuSbSe2
The BEC values represent the induced polarization when atoms are displaced, in this case, along the principal crystallographic axis directions. The net BEC values for displacements in the direction of each axis (a, b, or c) is shown below each tensor in square brackets.
