			The right part consists of a germanium crystal, one single point-contact made of gold, a lamp and a battery. The battery is placed with the positive pole versus the n-type area of the germanium crystal. The negative pole is placed versus the p-type area and as in the example of the reversed biased diode no current is present in the circuit. The lamp does not shine.
