SIMULATION OF MODEL HETEROGENEOUS SURFACES IN THE PRESENCE OF CORRELATION

We propose a general method to generate correlated energy landscapes f or model heterogeneous surfaces. It is based on the representation of an energy landscape as a superposition of exponentially correlated Gau ssian processes. This method is the extension of a previous work of Gi ona and Adrover to reconstruct binary lattice models of porous structu res to a random energy field with values between 0 and infinity. The a pplication to dual bond-site models is also developed.
