| Abstract | |
The Nernst coefficient for the quasi-one-dimensional metal, Li0.9Mo6O17, is found to be among the largest known for metals (nu similar or equal to 500 mu V/KT at T similar to 20 K), and is enhanced in a broad range of temperature by orders of magnitude over the value expected from Boltzmann theory for carrier diffusion. A comparatively small Seebeck coefficient implies that Li0.9Mo6O17 is bipolar with large, partial Seebeck coefficients of opposite sign. A very large thermomagnetic figure of merit, ZT similar to 0.5, is found at high field in the range T approximate to 35-50 K. (AU) | |
