Transverse Peltier effect in single crystals of the quasi-one-dimensional conductor, Li_0.9Mo₆O₁₇

Lithium purple bronze (Li_0.9Mo₆O₁₇) is a quasi-one-dimensional (q1D) conductor for which a large, p-type Seebeck coefficient transverse to its q1D chains coexists with n-type metallic behavior along the chains; a substantial transverse Peltier effect has been demonstrated.^a We will report on measurements of the transverse Peltier effect in a series of single crystals cut with their body axes at varying angles to the q1D chain direction. Comparisons of the data to theoretical models that employ known transport coefficients along the mutually perpendicular directions will be discussed.
