Surface chemical analysis. Auger electron spectroscopy and X-ray photoelectron spectroscopy. Determination of lateral resolution1 Scope This International Standard describes three methods for measuring the lateral resolution achievable in Auger electron spectrometers and X ray photoelectron spectrometers under defined settings. The straight edge method is suitable for instruments where the lateral resolution is expected to be larger than 1 m. The grid method is suitable if the lateral resolution is expected to be less than 1 m but more than 20 nm. The gold island method is
