Abstract

Callaway formula is used to invesfigate the lattice thermal conductivity for nine compounds from the

ternary group I-III-VI2 semicanductors at the temperature range from 5 to 300K. The maximum

conductivities are found to be inthe tenrperature range 5-15K.The effects of the Debye temperature on

lattice thermal conductivity as weil as maximum conductivity are invesfigated in some details. Many

imperical formula are found to relate these compounds with their lattice thermal conductivities. The

effects of carrier impurities (N) on this type of conductivity for the compound CuInSe2 are investigated

and the N^ dependence is fcrund.

Key Words : Lattice thermal conductivity, ternary compounds , semiconductor . impurity effects.
