Charge transfer in simple metallic alloys

D.J. González , J.A. Alonso

The concept of electronic charge transfer is a convenient one to study the ionic contribution to the chemical binding in simple metallic alloys. In this paper we analyse several possible definitions of charge transfer. This leads us to introduce several reference alloy states, such that charge transfer is defined as the net difference between the charge of an atomic cell in the reference alloy and the charge of the same cell in the ground state of the alloy. The requirements of internal consistency and consistency with empirical expectations permit us to discriminate between the possible reference states and to select a convenient definition of charge transfer.
