Abstract
We have investigated the atomic geometry and electronic structure of the Al As(110) surface by using the local density approximation of the density fun ctional theory and ab initio pseudopotentials. The structural and electroni c results have been used in the application of the adiabatic bond charge mo del for surface phonon studies. By comparing the results with other III-V(1 10) surfaces, we have obtained some general trends regarding the surface dy namics. (C) 2000 Elsevier Science B.V. All rights reserved.
