Current Reserach Projects The overall objective of the Fahlman research group is to design new and improved routes to interesting and industrially-useful 0-D, 1-D, and 2-D nanostructural materials. The following interdisciplinary projects are of ongoing interest to our group:
Precursor design and atomic layer deposition of high-k dielectric thin films (sole P.I., funded by the National Science Foundation - CHE). We are developing novel Hf complexes featuring beta-diketonato, beta-ketoiminato, beta-diketiminato, and guanidinato ligand systems - none of which have yet been reported in the literature. In addition, we have recently fabricated an atomic layer deposition system (ALD), that is capable of sub-monolayer control over film thicknesses. Real-time film thickness monitoring is also possible using a high-temperature in situ quartz crystal microbalance (QCM) sensor. Hafnium oxide thin films are of use for next-generation integrated circuitry, and we are primarily targeting nanocrystal-embedded HfO2 thin films for future nonvolatile memory (NVM) devices (e.g., flash memory sticks).
Design of high-energy density anode materials for improved Li-ion batteries (co-P.I. Veronica Barone (PHY), funded by the DoD - Tank and Automotive Research and Development Engineering Center, TARDEC). Focused on the synthesis and characterization of graphene nanoribbons (GNRs), and the quantification of Li uptake characteristics using electrochemical half-cell testing. The charge/discharge of GNRs and various other carbonaceous nanostructures will be compared to baseline materials such as graphite, graphene sheets, carbon nanotubes, etc. Empirical results will be compared to theoretical calculations performed by Dr. Barone (PHY). Design synthetic routes to produce materials with optimized morphologies and compositions for Li uptake. The first syntheses for GNRs have recently appeared in the literature, and we are the first group to report the Li capacity uptake of these nanostructures for Li-ion battery applications.
Novel design of quantum-dot sensitized solar cells (QDSSCs) (currently unfunded). We are developing a concept for more efficient QDSSCs that feature quantum dots of varying diameters (to absorb varying frequencies of the EM spectrum) covalently attached to vertically-aligned carbon nanotubes.
Solid-liquid-solid (SLS) growth of silicon nanowires (SiNWs) (currently unfunded). The most common method to grow SiNWs is vapor-liquid-solid (VLS), wherein a precursor vapor ( e.g., silane) supersaturates a molten nanosized catalyst at high temperature, forming a 1-D nanowire via crystallization. Our approach is much easier; to simply self-assemble Au nanoclusters onto a Si wafer, followed by thermal annealing (no precursor vapor required). We are working on controlling the morphology of the resultant nanowires by placing nanoclusters into lithographically-fabricated regions of the wafer, as well as studying the influence of temperature and Si substrate doping on the composition of the resultant nanowires.
