Description

The objective of the experiment P4.1.3.2 is to measure the current-voltage characteristic of a zener or Z-diode. Here, special attention is paid to the breakdown voltage in the reverse direction, as when this voltage level is reached the current rises abruptly. The current is due to charge carriers in the depletion layer, which, when accelerated by the applied voltage, ionize additional atoms of the semiconductor through collision.
