Electronic Devices Lecture-5 & 6: The Nature of the Atom & The Energy-band Theory of Crystals

In lecture 5: I discussed about the nature of the atom, in this we should remeber some expression for the GATE exam point of view.

In lecture 6: In this lecture, i discussed about the electronic configuration of 4th group elements, the orbital model of silicon atom then i discussed about the energy-band theory of crystals.
