Why the zener diode is used as a semiconductor device in voltage regulator?
A zener diode is a special kind of diode, which permits current to flow in the forward direction as normal, but it will also allow current to flow in the reverse direction when the voltage is above a certain value. This break over vlotage is the zener voltage which the diode is named after. See Related Links below.

What is avalanche voltage?
Avalanche voltage is the voltage value that causes a reverse-biased semiconductor junction to break down and conduct. Sometimes this is undesirable. A rectifier diode in a power supply that avalanches has failed. It can also be desirable. A Zener diode used as a regulator works by avalaching at a specific voltage, thus limiting the circuit voltage at that level.
What are zener diodes?
A diode (some people incorrectly call them rectifiers) is a semiconductor device that allows a current to flow in one direction. A Zener diode allows a reverse to current to flow at a defined voltage. A common application for them is as a voltage regulator. Named for C M Zener , US Physicist. A zener diode is a diode and like all diodes it will conduct in both directions. If a reversed voltage is applied it will breakdown and conduct current. Most diodes when they breakdown the reversed voltage cannot be predictable. However a zener diode when they do breakdown in the reverse voltage mode that voltage can be made as predictable and remain +/- % of the breakdown voltage. Therefore this steady voltage can be used as a regulator for instance or a definite voltage drop if need be.

What is the special property of a zener diode?
in the negative biasing it gives the constant voltage irrespective of limited current.......the voltage it provides in the negative biasing is known as 'zener voltage' due to this property zener voltage is used as voltage regulator........voltage regulator is a circuit which gives constant output even the input is changing.

Why you used semiconductor is your devices but why not conductor?
The kind of material used in a device depends on its requirements and functions. Semiconductors are used where we need moderate conductivity, conductors are used where we need very high conductivity. Junction diodes(a semiconductor device) allows electricity to pass in one direction and can be used as rectifier. Conductors can't do this. Transistors and LED are other applications of semiconductor. Note that generally devices are made of both conductors and semiconductors.
How much forward bias voltage is required for an led?
Conventional LEDs are made from a variety of semiconductor materials, and radiate at different wavelengths all the way from infrared to ultraviolet. Their forward voltage drops range from about 1 volt to 6 volts, depending on the materials used. Any bias greater than the diode's forward voltage drop illuminates the device.
