How intrinsic semiconductor can be made into extrinsic semiconductor?

∙ 13y ago
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.

What is an intrinsic semiconductor and what is an extrinsic semiconductor?
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
Is miscibility a extrinsic or intrinsic?
Extrinsic
Who founded intrinsic and extrinsic motivation?
Skinner
What extrinsic semiconductor is?
Those semiconductors in which some impurity atoms are embedded are known as extrinsic semiconductors.
What is meant by intrinsic semiconductor?
Semiconductor in pure form (i.e. without doping) is called intrinsic or i-type semiconductor. The no of charge carrier in this case is determined by the materials itself only and not by the impurities. In an intrinsic semiconductor number of excited free electron is equal to the number of holes.
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

Is silicon a extrinsic or intrinsic semiconductor?
silicon is intrinsic semiconductor until we add some impurities in it. the impurities are either of group 3 called acceptors which make p type or of group 5 called donors which make n type semiconductor.
What is the difference between intrinsic and extrinsic?
Extrinsic is external; intrinsic is internal.
What is the difference between intrinsic and extrinsic materials?
Intrinsic - A perfect semiconductor (ex: silicon) crystal with no impurities or lattice defects is called an intrinsic semiconductorExtrinsic - an extrinsic material is achieved by introducing impurities into the intrinsic material described above, such as doping silicon with boron atoms, such that the equilibrium carrier concentrations are different from the intrinsic carrier concentration.
Is miscibility a extrinsic or intrinsic?
Extrinsic
Is pressure a extrinsic or intrinsic?
Intrinsic
Which is a good conductor (Extrinsic or Intrinsic)?
Extrinsic
Difference between intrinsic and extrinsic feedback?
Difference between intrinsic and extrinsic feedback?
What is extrinsic and intrinsic?
A semiconductor material with electrical properties essentially characteristic of ideal pure crystal. Essentially silicon or germanium crystal with no measurable impurities
Is extrinsic a physical property?
Extrinsic is not a property; a property may be extrinsic or intrinsic.
Why does an extrinsic semiconductor behave like an intrinsic semiconductor at high temperature?
With the increase in temperature, the concentration of minority carriers starts increasing. Eventually, a temperature is reached called the critical temperature (85° C in case of germanium and 200° C in case of silicon) when the number of covalent bonds that are broken is very large and the number of holes is approximately equal to number of electrons. The extrinsic semiconductor now behaves essentially like an intrinsic semi-conductor.
