Abstract
A Patterson-like scheme is proposed for direct inversion of the conventiona l low-energy electron diffraction (LEED) intensity versus energy I(E) curve s, which is in contrast with the previously suggested holographic scheme. U sing the Si(111)-(7 X 7) and Si(113)-(3 X 2) surfaces as examples, high qua lity three-dimensional images, with a resolution better than 0.5 Angstrom, of both surface atoms and bulk atoms are obtained from the direct Patterson inversion of LEED-I(E) curves with the integral-energy phase-summing metho d.
