  Magneto-transport measurements on two dimensional van der Waals
heterostructures have recently shown signatures of uniaxial anisotropy. Such
measurements are almost exclusively performed in a Hall bar geometry which
makes it difficult to extract the full resistivity tensor. The goal of this
paper is to theoretically analyze anisotropic magneto-conductance in a
homogeneous disk geometry and to provide a closed form expression for the
electrical potential anywhere on the disk if the current source and drain are
located somewhere on the circumference. This expression can then be used to
experimentally extract the full conductivity tensor, and by a simple inversion,
the full resistivity tensor.
