Metal-Organic Synthesis
We emphasize the synthesis of main group and early transition-metal complexes having alkoxide (OR-), alkanethiolate (SR-), and dialkylamide (NR2-) ligands. These types of complexes are useful as precursors to inorganic thin films because of their ease of synthesis, physical properties, and reactivity.

Thin Film Preparation
We use the new complexes as synthetic precursors to inorganic thin films. The films are prepared using chemical vapor deposition, an important film synthesis technique. Typically, the targeted films have applications in microelectronic and energy conserving applications. The films are characterized thoroughly for composition and properties by using the CMC materials characterization facilities.
