| Abstract: | We report a fully self-consistent calculation of the electron number density, barrier height and adhesive energy as a function of separation in an aluminium-aluminum (100) contact. The local density approximation is used for exchange and correlation. The electron number density and barrier heights are strong functions of the separation. The range of strong chemical bonding is about 0.2 nm. |
