  • Abstract
    We show that it is possible with easy-to-program algorithms to reach spatial resolutions of the order of 108 grid points for computing the electric potential on 2D periodic lattices, such as the Si(111)7×7 surface. We have used a spectral Fourier technique and parallelized FFTs with OPEN_MP on SGI machines. This method can be easily extended to 3D.
