Abstract
A NOVEL MICROPROBE ANALYSIS TECHNIQUE WHICH HAS THE POTENTIAL FOR EXTREMELY SENSITIVE QUANTATIVE MEASUREMENTS OF SURFACE AND BULK CONCENTRATIONS AS WELL AS DEPTH PROFILES IS PROPOSED. THIS TECHNIQUE USES TWO PULSED LASERS TO VAPORIZE AND PROBE THE SURFACE LAYERS AND IS THUS CALLED PROFILE ANALYSIS BY LASER ASSISTED SPECTROSCOPY (PALAS). THIS PHASE I PROJECT WILL DEMONSTRATE THE FEASIBILITY OF PALAS BY MAKING MEASUREMENTS OF IMPURITY AND DOPANT CONCENTRATIONS IN GAAS AND INP. THESE MEASUREMENTS WILL BE PERFORMED IN SUCH A MANNER AS TO DEMONSTRATE THE UTILITY OF THE TECHNIQUE AS IN SITU DIAGNOSTIC FOR CONDITIONS GENERALLY ENCOUNTERED IN METALORGANIC CHEMICAL VAPOR DEPOSITION (MOCVD). EXTENSIONS OF THE TECHNIQUE TO HIGH AND ULTRAHIGH VACUUM CONDITIONS ENCOUNTERED IN MOLECULAR BEAM EPITAXY (MBE) AND COMPLEMENTARY SURFACE DIAGNOSTIC TECHIQUES ARE ALSO POSSIBLE.
