The extension of equation (3) to the case of broken translational invariance along the surface normal can now be easily guessed as ð rind ðQ; v; z; bÞ ¼ dz0 xðQ; v; z; z0 ÞFext ðQ; v; z0 ; bÞ; ð4Þ K. To´´ke´si et al. 34 where b is the z-coordinate of the external point charge. In the following ~ pz Þ with p2 ¼ P2 þ p2z Þ 3D vectors are denoted by lower case, ð~p ¼ ðP; while 2D vectors in the surface plane are denoted by capital letters. In the 2D Fourier representation, the Coulomb potential of an external unit point charge is given by 2p 2Qlz2bl e : ð5Þ Fext ðQ; v; z; bÞ ¼ Q The response function x is still local in the Fourier variables ðQ; vÞ but non-local in the coordinate z in which the translational symmetry is broken.

From the surface the asymptotic form (equation (51)) agrees very well with the numerical solution of the SRM and describes the stopping power very accurately. However, at smaller distances discrepancies indicate that contributions from shorter wavelengths become important. 2. Particle – hole excitation In the long-wave limit, the contribution from particle– hole excitation can be written as Im{gph SRM ðQ; vÞ} ¼ 2 2C~ Q 1 ¼ 22 2va; 2 p ðA~ þ 1Þ2 ðA~ þ 1Þ ð56Þ K.
