Group IV Nanocrystals: Silicon and Germanium

Silicon is the bedrock of modern technology, but the fundamental understanding nanostructured silicon is still evolving (as is it's sister semiconductor, germanium).  I worked with many talented scientists at NREL to improve our control of the surfaces of these materials, along with their optical and electronic properties.

Synthesis of Indium Nitride Nanocrystals

Nitride nanocrystals are historically very difficult to synthesize.  We develped a method to generate InN nanocrystals with size control using simple synthetic levers, and discovered a unique, tunable plasmonic property that had never before been observed in InN nanocrystals.  The results were published in the Journal of the American Chemical Society.

Mapping electronic states of quantum dots

Lead sulfide quantum dots were used as a model material to better understand and visualize descrete electronic states spacially within a single quantum dot.  This work was a collaboration with the Nazin lab at the University of Oregon which houses specialized Scanning Tunneling Spectroscopy (STS) equipment.

layer by layer chromophore assemblies

The majority of my Ph.D. work was dedicated to developing a novel layer-by-layer assembly process using "click" chemistry.  We successfully demonstrated a rapid, high-yielding process for the assembly of multiple chromophores on oxide surfaces.  In addition we created a proof-of-concept solar cell based on this technology that may someday improve the efficiency at which we convert light into electricity. Work continues in the lab of Peter Dinolfo to achieve this goal. My four first author publications are below.

Synthesis of novel organometallic compounds

Our team was searching for new compounds that could act as dearomatization agents in order to utilize inexpensive compounds as a chemical feedstock.  In pursuit of this goal we created many new fully characterized compounds with complete synthetic procedures.
