Introduction

The important feature of Auger electron spectroscopy and X-ray photoelectron spectroscopy is that they can obtain the surface area of solid samples (depth ≈ 1nm~10nm) Such analysis requires the determination of the intensity of the spectral peaks. Several peak intensity measurement methods are available for AES and XPS. In practice, the choice of method will depend on the type of sample being analyzed, the The performance of the instruments used and the available data acquisition and processing methods.
