Semiconductor diodes are made from the same Silicon, and occasionally Germanium, material that transistors, integrated circuits, etc. are made from.
Diodes used in early electronic devices were made from vacuum tubes.
Somewhat later diodes were made from finned stacks of Selenium.
Simple "Crystal Radios" use Galena (lead ore) crystals with a steel pin that is manipulated to find a spot that allows electrical current to flow in only one direction.

What best describes the function of a simple diode?
Diodes are used for a number of different purposes. Its most common function, however, is to act as a semi-conductor in a variety of commonly used household appliances.
What is shockky diode?
Its schotlky diode. schotlky diode is metal semi conducter junction. It has fast switchng speed. The cutting voltage of schotlky diode is about 0.2 volts.
What is extrinsic conductor?
Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. Two types of impurities are added to an extrinsic semi conductor. When impurities belonging to third group are called as trivalent or acceptor impurities such as boron, aluminum, indium or gallium when these impurities are added in pure semi conductors they form p-type semi conductor. And similarly when impurities belonging to group fifth called as penta valent or donor impurities such as arsenic, antimony, bismuth or phosphorus are added to a semi conductor they form N-type semi conductor .
What is baritt diode?
It is a barrier-injection transit-time, a high frequency - semi - structural element of micro-electronics, as the diode is one of the electronic components.
How cold does a semi conductor refrigerator get?
-3 to -7 c
In4001 diode what is IN in it?
It means that the semi conductor have only one pn junction
What is the difference in construction between power diode and simple diode?
Basically the semi-conductor junctions are a larger surface area and heat sinks are part of the design to dissipate heat.
Is ohm's law applicable to a reverse biased P-N junction?
no it is not applicable to any of the p-n junction diode.Since p-n junction diode is a semi conductor it is not applicable.U can take any semi conductor for example............
What type of laser is a diode laser?
A diode laser. Also, a continuous wave laser.A diode laser. Also, a solid state laser.A diode laser. Also, a high efficiency laser, comparing to other types of laser.It's a semi-conductor laser
What is the purpose of an cathode and an anode in a diode?
The cathode and anode are simply two terminals of a semi-conductor junction. In a normal diode, forward bias occurs when the anode is more positive than the cathode.
Is sodium a semi conductor?
No, sodium (Na) is a conductor not a semi conductor
How can you increase the conductivity of a semi conductor?
The conductivity of a semi-conductor can be increased by raising the temperature of the semi-conductor .
What are the examples of semiconductor devices?
lED, or light emitting diode, chips an others
What kind of a light source is light emitting diode?
The so-called LED light emitting diode is a semi-conductor light source. It is mainly used as a light indicator on many devices. It is also found in many applications.
In an experiment of finding energy gap of a semi conductor by using diode what is the junction voltage?
The junction voltage of the circuit should be nearlyb 1.5 to 2v to be maintained which is fixed voltage...
Is copper a conductor insulator or semi conductor?
