Brian William Goodfellow Department of Chemical Engineering Advisor: Brian Korgel First IGERT Semester: Fall 2006 IGERT Project Focus: Development of Cu(InxGa1-x)Se2 (CIGS) nanocrystal-based photovoltaics Alexander Ako Khajetoorians Department of Physics Advisor: Chih-Kang Shih; Co-Advisor: Allan Macdonald First IGERT Semester: Fall 2006 IGERT Project Focus: STM/STS of Dilute Magnetic Semiconductors and III-V interfaces Alfred Kwon-Hoon Lee Department of Physics Advisor: Alex de Lozanne First IGERT Semester: Fall 2006 IGERT Project Focus: My research involves the study of complex metal oxides using low temperature AFM and STM. In particular, we are interested in observing magnetic and electric domain structure and phase transitions through varying temperatures and fields using our home built multi-mode AFM. Our UHV STM has also been fruitful in investigating the electronic structure of these materials at low temperatures. Han-Jong Chia Department of Physics Advisor: John Markert First IGERT Semester: Spring 2007 IGERT Project Focus: I received a BA in economics and physics at Grinnell College and am currently pursuing a PhD in physics at the University of Texas at Austin. My research, under the guidance of Professor John Markert, is developing magnetic resonance force microscopy (MRFM) to study the properties of thin films. MRFM is a scanning probe microscopy technique that combines the cantilever based detection of atomic force microscopy (AFM) and pulsed magnetic fields of nuclear magnetic resonance (NMR). The synthesis of these two techniques yields nanometer scale spin resolution of various materials. I will use MRFM to obtain 3D spin images and relaxation times of organic and inorganic electronic materials. Down the road I intend to perform single nuclear spin detection feasibility studies by implementing high sensitivity cantilevers, novel forms of active feedback control, and millikelvin temperatures. Shannon Doane Lewis Department of Electrical and Computer Engineering Advisor: Ananth Dodabalapur First IGERT Semester: Spring 2007 IGERT Project Focus: Shannon Doane Lewis is a third year graduate student in Electrical and Computer Engineering (Solid State Electronics). She works for Professor Ananth Dodabalapur in the area of integrated organic and inorganic field effect transistors for chemical vapor sensing. She graduated from the California Institute of Technology with a degree in Chemical Engineering in 2005. Robert Alan May Department of Chemistry and Biochemistry Advisor: Keith Stevenson First IGERT Semester: Spring 2007 IGERT Project Focus: Benjamin Spivey Department of Chemical Engineering Advisor: John Ekerdt; Co-Advisor: Thomas Edgar First IGERT Semester: Spring 2007 IGERT Project Focus: My research project is focused on the growth of semiconducting vertical nanowires for use as chemical sensors. Currently, we have an APCVD system that has proven successful in growing vertical nanowires. Further research is expected to involve modeling the nanowire growth process, improving process control, and developing the nanowire pattern into an electrical sensing device.
