What is the use of a Zener diode?

A Zener diode is fabricated by heavily doping both p- and n-sides of the junctions. Explain, why ? Briefly explain the use of zener diode as a dc voltage regulator with the help of a circuit diagram.

An experiment is preformed to determine the I-V characteristics of a Zener diode, which has a protective resistance of R = 100 Omega , and maximum power of dissipation rating of 1 W. The minimum voltage range of the DC source in the circuit is :-
