CNT Transport Database
Description
Overview. The following is a database of experimental results for solution spun CNT fibers, provided by Rice University (Prof. Matteo Pasquali’s group) and Dexmat. Each tab represents a different experiment or physical property, as detailed below in a table of contents. In general, there are cryogenic measurements where 4-wire resistance, specific conductivity anisotropy, and Hall voltage are measured as a function of temperature, magnetic field strength, and magnetic field angle. This is primarily accomplished with our physical property measurement system (PPMS) at Wright Patterson AFB in Dayton Ohio were the lowest temperature possible was 1.9 K and maximum magnetic field was 9 T. We received supplemental measurements for high magnetic field (up to 60 T) al the National High Magnetic Field Laboratory at Los Alamos National Laboratory (LANL) and particularly low temperature (<65 mK) at the University of California Santa Barbra (Prof. Stefan Wilson’s group). In addition to cryogenic measurements, we included room temperature measurements of density, specific conductivity, conductivity, and aspect ratio of CNT materials. While peripheral to this study, we have also included a Raman database to include the raw spectra as well as specific Raman metrics. Finally, there are tabs that show 1) the numerical fits of cryogenic MR data to various transport models; 2) correlation tables of various material properties; 3) and a referenced compendium of applicable MR transport mechanisms in literature.
