| Abstract: | We have measured the effect of uniaxial stress along the (100), (101), (110) and (001) crystallographic directions and of hydrostatic pressure on the resistivity in several single crystal samples of Cd3As2 with carrier concentration n ? 2 × 1018cm?3 at room temperature. The results are interpreted considering a multi-valley model for the conduction band. With the aid of group theoretical investigation we conclude that the non-equivalent valleys are located at the points Γ and Δ in the Brillouin Zone. |
