Quantum Mechanical View of Electrical Conduction
In year 1926, Enrico Fermi and Paul Dirac established statistics for a system comprising of many
identical particles that obey Pauli exclusion principle. Certainly electron then must obey FermiD

Semiconductors (Intrinsic)
In the last chapter we discussed electronic structure of semiconducting materials. We saw that
based on their electronic structure, semiconducting materials can have varying electronic and

Electrical Conductivity in Metals
In this chapter we will discuss electrical conductivity in metals in the light of band theory of
electrons (chapter-5) and electron dynamics (chapter-6) discussed in previous chapters.

Electrons in Crystals Energy Bands
In chapter 4 we discussed how electrons behave in an empty lattice (empty lattice model) without
the effect of periodic potential that electrons must feel due to periodic arrangements of ions. In the

Electrons in Crystals

of electrons in a crystal. We will still describe electrons with their wave-function and solutions

Classical View of Electrical Conduction
In this chapter we will discuss the classical (or pre- quantum mechanical) view of DC
conductivity in metals. Electricity and electrical conduction was known for at least 2 centuries
