Une deuxième bande de conduction dans Cd3As2

Abstract
Magneto-Seebeck and magnetoresistance measurements were performed on polycrystalline samples of Cd3As2 at 80 °K and at 300 °K. The result gives an effective mass of m*(0) = 0.012m at the bottom of the first conduction band thereby agreeing with Blom and Schrama's determination. Heavily doped samples reveal the presence of a second conduction band whose minimum is 0.40 eV above the first minimum.
