Abstract: We prepared a series of (AgBiTe 2 ) 1- x (Ag 2 Te) x (0≤ x ≤1) composite materials by means of melting and cooling down. Their Hall coefficient and electrical conductivity were measured by the standard van der Pauw technique in the temperature range from 93 K to 283 K. The Hall mobility was calculated based on these data. Composite (AgBiTe 2 ) 0.125 (Ag 2 Te) 0.875 showed a higher Hall mobility than pure Ag 2 Te below 243 K. At approximately 143 K, the carrier type changes from p-type to n-type with increasing the temperature in Ag 2 Te. There is competition between the negative and positive carriers in both phases, resulting in enhancement of the mobility.
