Research Program and
Goals:
The overall objective of the Fahlman research group
is to design new and improved routes to interesting and industrially useful
nanostructural materials and thin films. Interdisciplinary projects involve the
following areas of concentration:
1. Synthetic Inorganic Chemistry - synthetic
techniques utilizing inert atmosphere manifolds (Schlenk lines) and glovebox are
necessary to obtain contaminant-free precursor compounds, suitable for use in
the chemical vapor deposition (CVD) of thin films.
2. Materials Chemistry - both traditional horizontal
hot-wall CVD (see schematic below) and supercritical fluid CVD methods are used
to deposit a variety of thin films. Characterization techniques such as
ellipsometry, scanning electron microscopy (SEM), tunneling electron microscopy
(TEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS),
and X-ray diffraction (XRD) are utilized to assess the nature of the resultant
film.
3. Physical Inorganic Chemistry - extensive empirical
(mass spectrometry, surface IR spectroscopy, XPS), and theoretical
investigations (using DFT methods) are carried out to identify likely surface
species, and the mechanism responsible for nucleation and growth of the thin
films.
The following projects are of current ongoing
interest to the group, finding applications for homeland security, as well as
advanced components such as fuel cells, sensors, microelectronic devices, and
future molecular electronic nanodevices.
1. Design of materials for low-temperature
degradation of chemical warfare agents and pesticides. 2. Supercritical fluid
facilitated growth of thin films and novel nanostructural materials. 3. Chemical
vapor deposition/characterization of Group 13 nitride and oxynitride thin films,
including the development of novel single-source, liquid precursors. 4. Nanotube-template
chemical vapor deposition of novel nanostructures.
