Module 6 : PHYSICS OF SEMICONDUCTOR DEVICES
Lecture 32 : Bonding in Solids
 
   Recap
   In this course you have learnt the following
Atoms combine to form solids through different types of bonds such as ionic, covalent, molecular and metallic
  bonds.
In ionic solids, atoms give out and receive electrons so that each atom completes octet configuration.
Semiconductors such as silicon and germanium are bonded covalently. In such bonding the atoms share electrons
  so that each one completes octet.
The effect of lattice potential on an otherwise free electron can be taken into account by defining an effective mass.
  Effective mass is proportional to the curvature of the band.
