Abstract
The Li and Ba atoms were intercalated into the Van der Waals gap of Bi 2Te 3 single crystals of n- and p-types. The resistivity, the Hall effect and the Shubnikov-de Haas effect were investigated in host single crystals and after an intercalation. The scattering of carriers is connected preferentially with acoustic phonons and does not change after intercalation. The mobility does not fall after intercalation as it does after doping the samples. The intercalation of metallic atoms causes the change in carrier concentration and, hence, the Fermi energy. But the intercalated samples possess the same energy spectrum as the host material.
