Let `n_(e)` and `n_(b)` are the number density of electrons and holes in extrinsic semiconductor then-

`n_(e)gt n_(b)`

`n_(e)lt n_(h)`

`n_(e)=n_(h)`

`n_(e) ne n_(h)`

Text Solution

Verified by Experts

The correct Answer is:

in extrinsic semicoductor `n_(e)ne n_(h)`
`n_(e)gt n_(h)("for n- type ") `
`n_(h)gt n_(e) ("for p - type" ) `

A pure semiconductor germanium or silicon, free of every impurity is called intrinsic semiconductor. A room temperature, a pure semiconductor has a very small number of current carriers (electrons and holes). Hence, its conductivity is low. When the impurity atoms of valence five or three are doped in a pure semiconductor, we get repectively n-type ot p-type extrinsic semiconductor. In case of a doped semiconductor. n_(e)n_(h)=n_(i)^(2) , where n_(e) and n_(h) are the number density of electrons and holes respectively and n_(i) is the number density of intrinsic charge carriers in a pure semiconductor. The conductivity of extrinsic semiconductor is much higher than that of intrinsic semiconductor. (i) Name two materials to be doped in pure semiconductor of silicon to get p-type semiconductor n-type semiconductor. (ii) What do you learn from the above study?
