Fermi surface dependence of the hall coefficient in quasi-2D molecular conductors

ABSTRACTWe report our results for the temperature dependence of the Hall coefficient and in-plane resistivity for the asymmetric-donor-based quasi-2D Molecular crystal τ- (P-S,S-DMEDT-TTF)2 (AuBr2)1(AuBr2)y (y≈0.75). Using a recent “geometrical representation” of the weak-field 2D Hall conductivity developed by N.P. Ong [Phys. Rev. B 43, 193 (1991)], we model the temperature dependence of these electronic transport properties in terms of the temperature dependence of the scattering path length and its anisotropy along the 2D Fermi surface.

ABSTRACTWe describe a recently constructed apparatus for the measurement of the Young's modulus and Poisson's ratio of free-standing sputtered multilayer films. In comparison with more conventional methods, this is expected to permit both measurement with lower uncertainties and interpretation which is more straightforward. A separate apparatus for the accurate measurement of the conductivity, magnetoresistance, and Hall coefficient of such systems has been prepared which will enable the contribution of Fermi surface-Brillouin zone interactions to the behaviour of these materials to be assessed.

The dependence of in-plane thermopower and Hall coefficient of Sr 2 RuO 4 on temperature are discussed. The apparently contradiction found in experimental data in the sign of these quantities at low temperature is clarified within a simple multi-band calculation. Then, by means of the Boltzmann equation and taking into account the Fermi surface curvature and different time collisions for the electrons in the t2g bands, the calculation is extended at high temperature.
