Surface Science is one of the major growth areas in modern research. It is a very vast field that involves the study of the physical and chemical phenomena that occur at surfaces and interfaces. Several physical and chemical analysis techniques are used to analyze surface composition. These include Low Energy Electron Diffraction (LEED) and Auger Electron Spectroscopy (AES).
LEED provides geometrical information about a specific surface while AES analyzes the chemical composition of surfaces. The information obtained from these techniques is crucial for the development of new microprocessors, solar cells, flat panel displays, hard disks, and thin film coatings.
