Why are semiconductors conducting the electricity called semi-conductors answer emphasized on SEMI?
JoppeDeQuint
Semiconductors are called that due to their elemental makeup, not because current is or is not flowing through them. Basically, semiconductors have a "good" number of electrons in their outer ring (valence electrons), making them (as my chemistry professor said...) "fat and happy" as they are.
Silicon is an example. It has 4 valence electrons, so it is happy. Elements in the third row of the Periodic Table want to have 0 (actually 8 in row 2), 4, or 8 valence electrons, and will try to steal or give away electrons to get there. This "stealing" or "giving away" causes elements to group together into molecules, but it also can cause an electrical charge build up if you can get enough atoms of one element that want electrons or want to give away electrons in a specific area.
This is why semiconductors are so important for modern circuits. Since they're "fat and happy", they don't influence whatever the designer is trying to build; they act as an unbiased base to build on.
To create electrical circuits, silicon is used as the foundation, and specific locations of the silicon disk have elements with (usually) 3 or 5 valence electrons placed onto it (called "doping"). This creates electrical potentials across the silicon; when put together in specific ways, this forms diodes, transistors, micro capacitors, exc.

Why semiconductor is called semiconductor not semiinsulator?
The purpose of semiconductors is to control the amount of conduction, not the amount of insulation.
Materials that are sometimes classified as insulators and sometimes as conductors are called?
semiconductors
What is doping in semiconductors?
semiconductors will be having some charged particles but for practical purpose the free charges should be available in abundant quantity. so in order to increase the charge particles number we add some impurity to these semiconductors . this process is called doping
When the conducting path for current flow bypasses the load it is called?
a short
What does Semiconductors mean?
A semiconductor is a material whose electrical conductivity properties fall between that of a conductor and that of an insulator.
A substance that will conduct electricity only under certain condition is called what?
semiconductors! SEMICONDUCTORS it will do it in some condition
What is a substance that carries electricity under certain circumstances but not under other circumstances?
A substance that carries electricity under certain circumstances but not under others is called a semiconductor.
How does the number of valence electrons in atoms of metalloids explain why metalloids are semiconductors?
Metalloids when used is electronics are called semiconductors.
Materials which lets electricity go through them are called?
Conductor are materials that conduct electricity. There are also semiconductors, which conduct electricity but not as well, and superconductors, which conduct electricity without resistance when very cold.
Why are metalloids semiconductors?
Metalloids when used is electronics are called semiconductors.
Why semiconductor is called semiconductor not semiinsulator?
The purpose of semiconductors is to control the amount of conduction, not the amount of insulation.
A material that prevents electrons from flowing freely is called?
The Materials are of three kinds:- Conductors- Semiconductors and- InsulatorsThe Insulators have the property to stop the flow of electricity, because they have less number of free electronics, which can conduct Electricity.
What is a Substances called that are good conductors of electricity?
When dissolved in water, electrolytes are able to conduct electricity. This is because they disassociate into negatively and positively charged particles.
Semiconductors are also called?
Solid state devices.
The elements in the Periodic Table which are semiconductors are called?
metalloids
What are the man-made impurites in semi-conductors called?
doping of semiconductors
Materials that are sometimes classified as insulators and sometimes as conductors are called?
semiconductors
