a) Heat produced or absorbed at a junction is proportional to the current by the junction.
b) This effect is produced when current is passed by junction of suitable materials.
c) It is reversible effect.
d) Heat exchange depends upon nature of conductors and temperature of the junctions.
e) It can be heating as well as cooling effect.
It is suitable for growing semi-conductively alloys like gallium arsenide. A typical arrangement is furnished with an induction heater that provides a controllable temperature grad
