Do compound semiconductors behave as intrinsic semiconductors?
Intrinsic refers to the doping -- intrinsic semiconductors are not doped. Whether compound or not, if they are not doped they are intrinsic.
What is tha extrinsic and intrinsic semiconductors?
The types of intrinsic semiconductors are mainly: silicon & germanium
at low temperature its forbidden gap is very large so it act as a insulater.
semiconductors are the conducors they are partially conduct electricity. And we can increase therir conductivity by using various method . They are Intrinsic method and extrinsic method . Intrinsic method is heating the semiconducter . Extrinsic method is doping. By using this method the conductivity of semiconductors is rapidly increases. Then we use semiconductors are prefferd to conductors
Intrinsic means no dopants. (a term used in semiconductors) So it means the same as pure.
at higher values of temperature the intrinsic carrier concentration become comparable to or greater than doping concentration in extrinsic semiconductors. thus majority and minority carrier concentration increases with increase in temperature and it behaves like intrinsic semiconductor.
intrinsic semiconductor : semiconductors which are in its extremely pure form are known as intrinsic semiconductor example : silicon, germanium extrinsic semiconductor : when a small amount of doping is added to intrinsic semiconductor it becomes extrinsic semiconductor
Semiconductors can either be intrinsic or extrinsic. Intrinsic semiconductors are elements that are in their pure form. These will usually have positive and negative sides because the electrons migrate towards one direction. On the other hand, extrinsic semiconductors are when the conductivity (or ability to make an electric charge with the electrons) are controlled by adding other atoms. These atoms that are added are called dopants. Dopants donate or receive electrons from the semiconductor to… Read More
Compound semiconductors have very low lifetime of charge carriers and hence they are not used for making Transistors and ICs.Rather it is used for making LEDs and LASER diodes.So the compound semiconductors are called photo-diodes. -M.R
Semiconductors have bulk resistivity in the range of 10-4 ohm-cm (heavily doped) to 103 ohm-cm (undoped, or intrinsic).
Answer An intrinsic semiconductor is a pure semiconductor. An extrinsic semiconductor is doped with trivalent of pentavalent impurities. semiconductors allow only a little amount of electricity to pass through them.they are of two types - n type and p type Are made of the semiconductor material in its purest from
Those semi conductors in which impurities are missing are known as intrinsic semiconductors. The electrical conductivity of the semiconductor depends upon the total no of electrons shifted to the conduction band from the valence band. This phenomenon is called as intrinsic conductivity.
intrinsic semiconductor is an un-doped semiconductor, in which there is no impurities added where as extrinsic semiconductor is a doped semiconductor, which has impurities in it. Doping is a process, involving adding dopant atoms to the intrinsic semiconductor, there by gives different electrical characteristics

But the two general characteristics are that metalloids often form amphoteric oxides often behave as semiconductors
intrinsic - where the semiconducting properties of the material occur naturally i.e. they are intrinsic to the material's nature. extrinsic - they semiconducting properties of the material are manufactured, by us, to make the material behave in the manner which we require. in intrinc s conductor no concentration gradient but in e.s.conductor there is a concentration gradient. there is eqal in conduction property but in extrinsic s.conductors due to con centration gradient conduction is increased… Read More
by adding pentavalent impurity in d pure semiconducters (like intrinsic semiconducters) is called n type semiconducters
Free electrons and holes are the charge carriers -not only in intrinsic semiconductors(these are the purest form of semiconductors-typically as pure as can be made available with the present technology) but also in extrinsic semiconductors(doped semiconductors). In intrinsic semiconductors,electron-hole pairs are created due to the natural processes like- absorption of heat energy from the surroundings absorption of energy from photons. this absorbed energy results in breakdown ofcovalant bonds in intrinsic semiconductors as a result of… Read More
What are the conditions for the fermi level to be exactly in the middle of the energy band gap of a semiconductor material?
For intrinsic semiconductors like silicon and germanium, the Fermi level is essentially halfway between the valence and conduction bands. You don't have to do anything; just keep the semiconductor intrinsic!
"As the temperature increases, more covalent bonds are broken, and more free electrons and positive empty states are created... The concentrations (#/cm3) of electrons and holes are important parameters in the characteristics of a semiconductor material, because they directly influence the magnitude of the current. An intrinsic semiconductor is a single-crystal semicon- ductor material with no other types of atoms within the crystal. In an intrinsic semiconductor, the densities of electrons and holes are equal… Read More

We call the smallest part of a compound a molecule of that compound. It (that molecule) will behave as any (all) the other molecules of the compound will. This molecule could be looked at as the "carrier" of the chemical identity of the compound.
There is no way to know stress levels in the body. It is intrinsic you just feel it. If the stress is more it causes your body to behave negatively.
Pure Silicon Carbide(SiC) is AA intrinsic semiconductor material(Group IV).
A piece of intrinsic (pure) silicon at room temperature has, at any instant, a number of conduction-band (free) electrons bthat are unattached to any atom and are essentially drifting randomly throughout the material. Also, and equal number of holes are created in the valence band when these electrons jump into the conductance band.

Actually material which are having conductivity between metals and insulators. Elemental Semiconductor:- They are single elemental semiconductors. And they belong to the group IV of the periodic table. Ex:- Si, Ge, Sn etc... Compound Semiconductors:- They are formed by using two or more elements. they are synthesized using elements from group II - IV & group III - V.
Transistors are made out of semiconductors, yes.
As temperature increases the resistance of semiconductors decreases. This means that semiconductors have a negative temperature coefficient.
The two metalloids that are semiconductors are boron and silicon. there are more than two metalloids that are semiconductors

To be exact EF should be at the valence band edge (EV) at 0K because no energy state above EV are occupied at 0K; however, for intrinsic semiconductors there are no states in the band gap anyway, so placing the EF anywhere in the band gap including conduction band edge does not add any states as being occupied. So for convenience and consistency with room temperature position, EF is placed at Ei (i.e. room temperature… Read More
The population of Horizon Semiconductors is 2,007.
Resistivity is the resistance, in ohms, between the opposite faces of a 1-metre-cube of a material. For metals, resistivity is in the region of 0.0000001 ohm-metre. For semiconductors, it is much higher - it is in the region of 0.01 ohm-metres.

Metalloids when used is electronics are called semiconductors.
No, they behave in a similar way. When an ionic compound (like NaCl) dissolves, its atoms separate and become free particles within the solution.
Semiconductors are commonly used in electronic circuit boards. Semiconductors are the common reasons why capacitors are able to carry out their tasks in a circuit board.
There are two types of extrinsic semiconductors. They are a) n-type semiconductors b) p-type semiconductors. n-type semiconductors: These are impure by fifth group elements like phosphorous, arsenic, antimony. In this type of semiconductors majority charge carriers are electrons and minority charge carriers are holes. These are donors of electrons. p-type semiconductors: These are impure by third group elements like boron,indium. In this type of semiconductors majority charge carriers are holes and minority charge carriers are… Read More

This is not a compound sentence. A compound sentence is one that can be broken into two separate yet complete thoughts. As this one is a sentence where the first part is dependent on the second and can not be split.
Water is an amphoteric compound because when it reacts with acids it behaves as an acid and conversely it will behave as a base.
since n type semiconductors have high mobility for electrons, they are preffered over ptype
