Currently evaluating giant magnetoresistive (GMR) devices to replace devices based on conventional pickup coils. This project facilitates the detection of deeply buried flaws in conducting materials, e.g., airline skins, and therefore has great practical applications. The use of giant magnetoresistance (GMR) sensors in electromagnetic (EM) nondestructive evaluation has been increasing rapidly. For example, here at LaRC a rotating GMR probe has been incorporated into a product to detect deeply buried flaws in aerospace structures, specifically at rivet joints. A spatial filtering scheme was developed that enhances the output, while not significantly increasing the number of false alarms. For this application and for many similar ones, research to create smaller, sensitive and more energy-efficient EM sensors should be aggressively pursued. Recent theoretical and experimental work on spin coherent transport supports the feasibility of carbon nanotube based magnetic tunnel junctions. Such devices contain single-walled carbon nanotubes that connect two ferromagnetic electrodes. The ability to model the electrical behavior of such junctions, for realistic system sizes, has been developed at Langley, and these tight-binding model calculations have been extended. We use junction fabrication methods that take advantage of NESB's new e-beam lithography and nano-manipulation capabilities.

Co-investigator: Professor F. Ohuchi.
Studied NF3 plasma as an etchant on Si. Used a MKS 252C valve controller with a throttle valve to greatly stabilize the etching plasma pressure. Performed all of the etches, varying processing conditions such as plasma energy, ratio of NF3 to diluent (argon or helium), and total chamber pressure. Etch rates were obtained for each etch, using a physical mask and an Alphastep profilometer. Used a Digital Instruments Multi-Mode Scanning Probe Microscope to characterize the roughness and size distribution of surface features. Also studied NF3 Etching Reaction with GaAs(100) using X-ray Photoelectron Spectroscopy.

Located carbon nanotubes and attached them to AFM cantilevers for high-spatial-resolution imaging of biological molecules (DNA-protein complexes) of interest to Prof. Ruedi Aebersold of Molecular Biotechnology. Electron microscope images of tips with attached nanotubes are posted under "research interests." A hard silicon grid and some lambda DNA were successfully imaged, but the tips did not outperform conventional ones in imaging DNA.

Produced metal constrictions with diameters as narrow as 3 nm which can determine the energy dependence of electron scattering through the voltage dependence of the device resistance. Studied giant magnetoresistance materials, in both multilayer and co-evaporated materials, using this method of "point contact spectroscopy". Developed a data acquisition system using a 16 bit A/D board and the LabVIEW software package. Learned nanofabrication techniques at the Cornell Nanofabrication Facility. Used ultrahigh vacuum systems, physical vapor deposition and sputtering techniques, a dilution refrigerator, and other low temperature apparatus.
