Potential and negative electric field around O1i in (a) the vacant and (b) the occupied cages on the plane of Al1iv, O1i and Al1aiv. Red solid contours are positive and blue broken ones are negative. The contours are at 0.2 e Å−1. The arrows indicate the direction and strength of the electric field acting on a negative unit charge. For details see text.
