Abstract

The purpose of this thesis is to provide a comprehensive overview of two important techniques (low energy electron diffraction (LEED) and Auger electron spectroscopy (AES)) used in the study of surface phenomena. Within this context, a LEED study of Fe-33%Ni near its Martensitic transition temperature (155K) was done to determine if there is a surface precursor to the Martensitic transformation. Based on visual comparison of experimental and theoretical I-V curves for two diffracted beams, it has been concluded that at 166K no such precursor is apparent. The taking of LEED data nearer the transition temperature was made impossible by the unexpected transformation of our sample during cooling. Further study with a new sample is planned for the immediate future.
