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.
Difference between intrinsic and exterinsic semiconductors?
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 typeAre made of the semiconductor material in its purest from
Can LED be manufactured by intrinsic semi conductor?
LED is short for Light Emitting Diode. It is a special type of diode that emits light when it is forward biased. Diodes are made using N doped and P doped semiconductors(not intrinsic/pure.) They form a junction that allows the system to act as a diode. So in short, no. However these doped semiconductors were made using pure(intrinsic) semiconductors. Therefore depending on how far you trace back the process the semiconductors were once intrinsic. So depending on how you look at it, yes.
Pentavalent elements are added to intrinsic semiconductors elements to produce what type?
N
Why we not use pure silicon instead of intrinsic silicon?
Intrinsic means no dopants. (a term used in semiconductors) So it means the same as pure.
Resistivity range of semiconductors lies between the range of?
Semiconductors have bulk resistivity in the range of 10-4 ohm-cm (heavily doped) to 103 ohm-cm (undoped, or intrinsic).
What are the advantage of semiconductor over conductor?
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
What are the semiconductors in the periodic table?
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 make impure.
Why intrinsic semiconductors behave like insulator at low temperature?
at low temperature its forbidden gap is very large so it act as a insulater.
How intrinsic semiconductor can be made into extrinsic semiconductor?
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.
How do you obtain n type semiconductors?
by adding pentavalent impurity in d pure semiconducters (like intrinsic semiconducters) is called n type semiconducters
What roles do free electrons and holes play in intrinsic semiconductor?
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 surroundingsabsorption of energy from photons.this absorbed energy results in breakdown ofcovalant bonds in intrinsic semiconductors as a result of which electron-hole pairs are created.It is this electron hole pair which is responsible for carrying the current through the intrinsic semiconductor when a potential difference is applied across it.In extrinsic semiconductor the case is slightly different-here, we have-majority charge carriers and minority charge carriers.in an n-type semiconductor-majority charge carriers are the electrons contributed by the pentavalent impurities while the minority charge carriers are the holes which are generated as electron-hole pairs due to natural processes discussed above.in p-type semiconductor-majority charge carriers are the holes contributed by trivalent impuritieswhereas the minority charge carriers are the electronswhich are generated as electron-hole pairs due to natural processes discussed above.these are the majority charge carriers which contribute heavily in the flow of current through the extrinsic semiconductors than the minority charge carriers.I suggest you to please go through mass action law and law of electrical neutrality of semiconductors for better understanding.
