To discuss the possibility of improvement in thermoelectric properties of SiGe crystal,the thermoelectric properties of several different silicon-germanium alloys with different content,different orientation and different electric conductive type at the temperature range of 300-1100K were investigated.As seen in the experiment result,the absolute value of Seebeck coefficient fluctuates in 200-600 μV/K in the whole temperature range investigated.In the present paper,the relationships of Seebeck coefficient against content,orientation,electric conductive type and electrical resistivity were summarized in detail.The Seebeck coefficient of the sample with 111 orientation is smaller than that of the sample with 100 orientation at the same temperature.Absolute value of P-type are larger than that of N-type,pure Ge except.But with the increasing of temperature,the absolute value of pure Ge decreased many times as quickly as other specimens.Moreover,electrical resistivity not only can influence the figure of merit,but also can influence the absolute of Seebeck coefficient.
