Abstract :
By using the low thermal conductivity of SiGe to increase the average temperature along the pn-junction of the structure, the efficiency and power output of our thermoelectric elements can be increased dramatically. Further improvement can be achieved by using optimized graded Ge content to fully adapt the temperature distribution to our needs
