Comment on 'Anisotropic scattering in angular-dependent magnetoresistance oscillations of quasi-two-dimensional and quasi-one-dimensional metals: Beyond the relaxation-time approximation'

摘要

Recently, Smith and McKenzie [Phys. Rev. B 77, 235123 (2008)] used Boltzmann theory to calculate expressions for the interlayer resistivity in quasi-one-dimensional and quasi-two-dimensional metals for an arbitrary elastic collision integral. In this Comment I point out that their treatment of the equations of motion leads to an error in their expressions, and I derive corrected expressions for the interlayer conductivity in quasi-one-dimensional and quasi-two-dimensional metals in the presence of anisotropic scattering.
