Semiconductor raw materials like silicon, germanium, and selenium are the purest substances that you will have a chance to encounter. However the process of making semiconductor devices deliberately contaminate the semiconductor with controlled amounts of various impurities.
Other semiconductors like gallium arsenide and the semiconductors used in LEDs are alloys.
Other semiconductors like cadmium sulfide and lead sulfide (galena) are compounds.
What else can I help you with?
Why are tin and lead not used as semiconductor?
because they are not semiconductors. They are metals and rather good conductors.
Is non metal a semi conductor?
No. Nonmetals are generally non-conductors. Metalloids are usually semiconductors.
Are semiconductors noble gases?
No, semiconductors are not noble gases. Semiconductors are a type of material that can conduct electricity under certain conditions, while noble gases are a group of non-reactive elements in the periodic table.
Will hall voltage be identical in semiconductors and conductors?
No, the Hall voltage will not be identical in semiconductors and conductors due to differences in charge carrier concentration and mobility. In conductors, there are typically more free charge carriers, leading to a different Hall voltage response compared to semiconductors, which have fewer charge carriers and can also have both electrons and holes contributing to the Hall effect. Additionally, the type of charge carriers affects the sign and magnitude of the Hall voltage in these materials.
How are substances classified on the basis of resistivity?
Substances are classified based on their resistivity as conductors, insulators, or semiconductors. Conductors have low resistivity and easily allow the flow of electric current. Insulators have high resistivity and inhibit the flow of electric current. Semiconductors have resistivity values between conductors and insulators, making them suitable for controlling the flow of current in electronic devices.
Do nonmetals tend to be just as good conductors as metal?
No, nonmetals tend to be insulators. Some (e.g. carbon) are poor conductors. Semiconductors (e.g. silicon and germanium) in their pure form are insulators but when doped with the right impurities can conduct as good as metals. This is why they are called semiconductors.
Which statement is true of semiconductors?
Semiconductors do not conduct current as well as conductors.
What are nonmetal that are conductors of heat and electricity?
Semiconductors
How are materials classified on the basis of resistivity?
Materials can be classified based on their resistivity as conductors, semiconductors, or insulators. Conductors have low resistivity, allowing electric current to flow easily. Semiconductors have resistivity in between conductors and insulators, and their conductivity can be controlled. Insulators have high resistivity and do not allow electric current to flow easily.
Where does electric current pass?
Electric current passes through substances called "conductors", as well as "semiconductors". Conductors include all metals, and any liquid with ions in it.Electric current passes through substances called "conductors", as well as "semiconductors".

Elements that are intermediate conductors of heat and electricity?
semiconductors
What are nonmetals that are intermediate conductors of heat and electricity?
Semiconductors
What shows how conductors insulators superconductors and semiconductors rank in order of least resistance to most resistance?
Superconductors have no resistance, making them the best conductors. Semiconductors have moderate resistance. Conductors have low resistance, making them better conductors than insulators, which have high resistance, making them the poorest conductors.
Substance in between conductors and insulators used in transistors?
Semiconductors
What is conductors insulators superconductors and semiconductors rank in order of least resistance to most resistance?
Superconductors have no resistance. Conductors have low resistance, semiconductors have intermediate resistance, and insulators have high resistance.
What are pure semiconductors?
silicon and germanium
What are Conductors Insulators Semiconductors?
Conductors are materials that allow electricity to flow easily, like metals. Insulators are materials that do not allow electricity to flow, like rubber or glass. Semiconductors are materials that have properties between conductors and insulators, and are commonly used in electronics.
