Is pressure a extrinsic or intrinsic?
Intrinsic
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 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
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.
What are trivalent and pentavalent impurities?
Doping is the process of adding impurity atoms to intrinsic silicon or germanium to improve the conductivity of the semiconductor. The term impurity is used to describe the doping elements. Two element types are used for doping: trivalent and pentavalent. A trivalent element is one that has three valence electrons A pentavalent element is one that has five valence electrons. When trivalent atoms are added to intrinsic semiconductors, the resulting material is called a p-type material. When pentavalent impurity atoms are used, the resulting material is called an n-type material. The most commonly used doping elements are listed below. Commonly Used Doping Elements Trivalent Impurities To make p-type Aluminum (Al) Gallium (Ga) Boron (B) Indium (In) Pentavalent Impurities To make n-type Phosphorus (P) Arsenic (As) Antimony (Sb) Bismuth (Bi)
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?
Intrinsic feedback comes from within the individual, such as the feeling of accomplishment from completing a task. Extrinsic feedback is information provided by an external source, like a teacher or coach, to guide performance or skill development.
Why you do not take pure silicon and use extrinsic silicon material?
Extrinsic silicon is just silicon that has been doped. So it has different semiconducting propeties from pure (intrinsic) silicon. Why anyone needed to introduce the words intrinsic and extrinsic into the subject always baffled me.
Is extrinsic a physical property?
Extrinsic is not a property; a property may be extrinsic or intrinsic.
Is lambda max an intrinsic or extrinsic property?
intrinsic property
What is extrinsic and intrinsic evil?
Intrinsic(inherent,or inborn)evil.
What are the intrinsic and extrinsic properties of matter?
Extrinsic properties can be affected by the factors while Intrinsic is unaffected by the factors... (I'm unsure)
What is the difference between intrinsic and extrinsic sugars?
The difference between intrinsic and extrinsic sugars is that intrinsic sugars are sugars that occur naturally in the cellular structure of food while extrinsic sugars are added or are free in food. Intrinsic sugars are mostly found in fruits and vegetables. Extrinsic sugars are divided into milk sugars or lactose and non milk extrinsic sugars which are added sugar and honey. - Intrinsic motivation is your own personal motivation that comes from inside you. It is self motivation personal gain, satisfaction, or enjoyment. Extrinsic motivation is from external sources, money, coercion, fame, fortune, recognition. - Extrinsic is external; intrinsic is internal Intrinsic is inner or from inside and extrinsic is outer or from outside
