Question # 1

Distinguished between elasticity and plasticity.

  • Ans 1: Elasticity: In deformed crystalline solid,the atoms return to their equilibrium position after the removal of external force.This ability of the body to return to its original shape is called elasticity.
  • Ans 2: Plasticity:If the stress is increased beyond elastic limit,the specimen becomes permanently deformed.This is called plasticity.

Question # 1

How n type semiconductors are formed?

  • Ans 1: When a silicon crystal is doped with a pentavalent element,e.g arsenic,antimony or phosphorus etc.four valence electrons of the impurity atom form covalent bond with the four neighbouring Si atoms,while the fifth valence electrons provide a free electron in the crystal.Such a doped semiconductor is called n type semiconductor.
