Research in our group is focused on the growth, modification and characterization
of surfaces and interfaces for applications in sensors, energetic materials,
catalysis, and molecular electronics and data storage. Students in my
group us a variety of surface analysis techniques including scanning probe
microscopy, x-ray photoelectron spectroscopy, temperature programmed desorption,
ellipsometry, and surface plasmon spectroscopy. Below is a description
of some of the current projects in the group.
Surface and materials chemistry
Growth and characterization of half-metallic ferromagnetic films for
A current project involves the growth of semiconducting organic films
on half-metallic ferromagnetic substrates to fabricate organic spin-valves.
This research is supported through the NSF funded Materials Research Science
and Engineering Center on campus.
Growth and characterization of metals on nitramines
This project involves the deposition and characterization of combustible
metals on nitramines. We are collaborating with scientists at the Naval
Warfare Center to increase the performance of underwater energetic materials.
The Office of Naval Research funds this work.
We are studying charge storage in redox-gradient dendrimers synthesized
by Dr. Blackstock through a variety of scanning probe microscopy and electrochemical
methods. The long-term goal of this project is to realize an ultra high-density
molecular based memory. The research is supported through the NSF funded
Materials Research Science and Engineering Center on campus.
