Current Question (ID: 17997)

Question:

$\text{Doping causes-}$ $1. \text{Dislocation defect.}$ $2. \text{Schottky defect.}$ $3. \text{Frenkel defect.}$ $4. \text{Electronic defect.}$

Options:

1. $\text{Dislocation defect.}$
2. $\text{Schottky defect.}$
3. $\text{Frenkel defect.}$
4. $\text{Electronic defect.}$

Solution:

$\text{HINT: Conductivity of semiconductors increased by adding an appropriate amount of suitable impurity.}$ $\text{Explanation:}$ $\text{In semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor.}$ $\text{When electron-rich or electron-deficient impurity is added to a perfect crystal it introduces electronic defects in them.}$
