Comparison is made between Auger and LEED data recorded from cleaved and polished-sputtered-annealed InP(110) surfaces. The qualitative Auger analysis indicates that the sputtered-annealed surface does not quite reach stoichiometry and that LEED measurements are made from a surface presenting an In rich composition. The LEED measurements taken from the two surfaces are compared and found essentially similar, proving that the atomic reconstruction of the ordered portions of the two surfaces are identical. A short description is given of the structure model found by single and multiple scattering computations.
