Effects of temperature on different material types
Band theory of various materials. How P type and N type sonductors are formed and how they compare with each other.
PN junction - how it is formed and its voltage-current characteristics.
Applications of the diode

Interest in the subject of electronics

This course is part 1 of the series on electronics. It captures the fundamental principles in electronics required to be able to understand higher concepts in the field. Area covered include materials and how their conductivity varies with change in temperature. Doping in sonductors and band theory of materials are all captured here. We go on with how a PN junction is formed, behavior of the depletion region of a PN junction and the IV characteristics of a PN junction. One application of the diode in switching power supply is shared to introduce the section on diode applications.
The course is in 4 sections
Section 1– Atoms, conductors, insulators & semi-conductors: In this lesson you will learn the basics of an atom. The various materials we have on the based on the material's ability to conduct electricity and how temperature affects each of these materials. We will end with an opener into the subject of sonductors.
Section 2 – Doping: You will learn in this lesson what doping means in electronics, how doping is done, the conditions associated with doping and the types of doping
Section 3 – Band theory of insulators, conductors, and sonductors: You will learn how the structure of materials dictate their ability to conduct electricity based on energy levels.
Section 4 – Comparing N-type and P-type Sonductors, PN junction and its characteristics: At the end of this section, you will know how P type and N type sonductors compare with each other, how a PN junction is formed ,and the IV characteristics of a PN junction.
