When cations and anions are missing from their correct lattice site then a hole will arise which is responsible for p - type semiconductor.

 

 

Schottky defect -

Defect in which equal number of cation and anions are missing from their crystal lattice site called schottky defect .

In this defect density of crystal deecreases and crystal behaves as P - type semiconductor , conductivity of crystal increases .

% of missing unit = (\frac{d_{theoretical} - d_{experimental}}{d_{theoretical}}) \times 100

- wherein

This defect is common in the compound having high coordination number and almost equal size of cation and anion.

ex : NaCl , KCl , CsCl , AgBr etc

 

 


Option 1)

p - type semiconductor

This is correct

Option 2)

n - type semiconductor

This is incorrect

Option 3)

both p and n- type

This is incorrect

Option 4)

None of the above

This is incorrect
