%X An experimental investigation into the effect of heat treatment on morphologyand thermoelectric properties of SiGe:GaP alloys is reported.Attempt was made to correlate thechangas in the thermoelectric properties with these in matarial's morphology.The results indi-cate that a reduction in the lattice thermal conductivity of the alloys is partially attributed to thechanges in material's morphology,i.e.the appearance of Ge-rich regions and the disappearanceof Si-rich regions.However,no correlation has been found between the material's morphologyand the observed substantial changes in electrical properties of the alloys.Nevertheless,the ex-perimental results show that the alloys with a morphology consisting of only host matrix andGe-rich regions exhibit the largest thermoelectric figure of merit.
