Rosa Leon
Position:
Senior Member of Technical staff
Education:
Ph.D.
Materials Science, University of California, Berkeley, CA, 1992
Dissertation:
Properties of Cu in GaAs and InP. Most outstanding result was the
finding of a new mechanism to obtain semi-insulating InP. Proposed
general model for the behavior of Cu in semiconductors, based on diffusion
mechanism, electrical behavior and precipitate formation. Examination
Fields: Defects in Semiconductors, Solid State Physics, Characterization
of Materials (electrical, optical and structural).
