Possible emergence of nematic superconductivity that breaks its underlying lattice symmetry in doped topological insulator Bi2Se3,establishes this system as a unique candidate of topological superconductors. Exclusion of possible extrinsic causes for the two-fold superconductivity is essential to clarify its topological nature. Here, we present electrical transport on SrxBi2Se3 superconductors with rectangular and circular geometries. The occurrence of the two-fold symmetric in-plane upper critical field Hc2 is found to be weakly geometry dependent. However, the anisotropic ratio between the maximum and minimum in-plane upper critical fields varies significantly among samples with different shapes. Compared with the rectangular sample, the anisotropic ratio is largely suppressed in the circular sample which has higher geometric rotational symmetry. Our results imply that sample geometry plays a subdominant role, but circular shape is more ideal to reveal the two-fold superconductivity of SrxBi2Se3 in the vortex state.
