What effect do added impurities have on semiconductor conductivity?
It is called as DOPING. Doping is the process in which you add an impurity to a pure semiconductor to increase its conductivity. While doping is done, crystal structure of semiconductor is not disturbed.
Why are doping materials called impurities?
because they change a materiel's property from it original form (pure form), to a different property from due to doping fig of semiconductor distrot
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.
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 construct an n type semiconductor?
An n-type semiconductor is formed by doping a pure semiconductor (silicon or germanium, for example) with atoms of a Group V element, typically phosphorus or arsenic. The dopant may be introduced when the crystal is formed or later, by diffusion or ion implantation.
What will happen when doped semiconductor is heated will its conductivity increase or decrease?
Doping a semiconductor means to introduce impurities to the semiconductor in order to alter it. For the most part, doping a semiconductor increases its conductivity.
What is mean by doping?
Doping is a process of adding some impurity in pure material or pure semiconductor.
Will a semiconductor remain electrically neutral after doping?
Yes
What kind of semiconductor is produced by adding indium in semiconductor crystals?
it is metal.. so not used for doping.
Carrier of electric current in germanium semiconductor?
electrons or holes depending on doping, as in any semiconductor.
What term is given to the process of rearranging electrons in a semiconductor by adding atoms of other elements?
doping
What is mean by doping procesess?
Doping is a process of adding some impurity in pure material or pure semiconductor.

What do you call of a semiconductor decreases while doping increases?
Impurity
How Significant is the Role of Doping in Semiconductor's Conductivity?
Very. Doping determines the conductivity, pure silicon is a good insulator.
What is the process of adding some impurities to semiconductor material?
Its called doping.
What is the material of adding some impurities to semiconductor material?
Its called doping.
