The Li and Ba atoms were intercalated into the van der Waals gaps of Bi 2 Te 3 , solid solutions based on Bi 2 Te 3 and β-polytype of InSe single crystals of nand p-types. The temperature dependence of resistivity, the Hall effect and the Shubnikov- de Haas effect were investigated in host single crystals and after an inter calation. The intercalation of metallic atoms causes a change in carrier concentration and hence, the Fermi energy. The intercalated Bi 2 Te 3 samples possess the same six-ellipsoidal Fermi surface as the host material 2D weak localisation was observed in the host n-InSe which was suppressed by an intercalation
