A computer simulation of auger electron spectroscopy

Recently a powerful method of investigation has been possible through the advent of modern high speed computers. This is method of computer simulation or modeling. We believe, we understand what the fundamental laws that govern the system are but we are simply unable to work out their consequence. The simulation techniques try to give a comprehensive coverage of the work that has been done which would involve confusion. It extends the work study and reveals the different aspects of physical knowledge that are obscured. The auger electron spectroscopy provides a comprehensive picture about the elemental composition of surfaces. Each element has a characteristic auger energy, which can serve as a kind of chemical signature of the element. The detection is accomplished through a retarding field analyzer a lock-in amplifier and an AC modulation technique
