Prof. William A. Goddard, III
Charles and Mary Ferkel Professor of Chemistry and Applied Physics
Director, Materials and Process Simulation Center
B.S. - University of California, Los Angeles, 1960.
Ph.D. - California Institute of Technology, 1965.
Professor Goddard's research focuses on:
- Developing new methods for theory including:
- quantum mechanics for the electronic wavefunctions of large
molecules and crystals, including the many-body effects needed to
- force fields to describe the dynamics of atomic motions[4,5]
- molecular dynamics of large molecules and solids to determine
the structure, vibrations, and dynamical processes of materials[6-8]
- statistical mechanics to describe phase diagrams (mixtures of
molecules and polymers; metallic alloys)
- Implementation of these methods in efficient software for high
speed calculations using massively parallel computers
- Applications of these methods to important problems in the
chemistry, materials, and biological sciences including:
- prediction of protein tertiary structure from primary sequence
- mechanisms of catalytic reactions on surfaces (heterogeneous)
and in solution (homogeneous)[9,10]
- reconstruction of semiconductor, ceramic, and polymer surfaces
- growth of semiconductors and ceramics using molecular beam
epitaxy (MPE) and chemical vapor deposition (CVD)
- properties of amorphous polymers (moduli, surface tension, gas
diffusion, glass temperature, hyperpolarizabilities).
- properties at semiconductor heterojunctions
- structure and energetics of protein/DNA complexes[12,13]
- Application of these methods to important industrial
problems. Current projects include:
- VPO catalysis - mechanism of highly selective oxidation of
butane to maleic anhydride; develop experimental tests for the
mechanism and extend to new substrates
- HgCdTe - mechanism of MBE growth for (100) Hg1-xCdxTe;
develop a growth strategy for incorporating As at Te sites (p type
doping) and for preventing Hg vacancies
- nylon - determine how the properties of nylon (moduli, melting
point) are related to molecular structure; learn how to prevent
deleterious incorporation of H2O.
- gas diffusion in polymers - characterize diffusion of small gases
(CO2, O2 etc.) in copolymers; determine how it depends on
character of copolymer.
- corrosion inhibitors - replace imidazolines.
- wear inhibitors - replace Zn dithioalkylether phosphates.
- scale inhibitors - replace phosphonate amines.
- scale dissolvers - replace EDTA.
- demulsifiers - find effective ones for asphaltines.
