Abstract
A resistor for the treatment of materials, such as for the production of monocrystals by the planar resistor method includes an electrically conductive thin plate having a zone with a plurality of holes. With respect to an electric current flowing in the plate substantially parallel to its faces, the plate has lower electrical resistance in a peripheral area of said zone than in the central portion thereof.
