I am Swarit Mahalsekar, a biomedical engineer, I am also an online instructor at more than 3 platforms. I am also the founder of the "practical-buddy" website for analog electronics. I had done lots of projects regarding electronics so I have good knowledge of using different software like Thinkercad, Proteus, Eagle, etc. So whatever course I would be launching I will make sure that I will not only teach you the concepts theoretically but also enhancing your technical skills with the h

About This Course

Who this course is for:

  • Anyone who wants to learn semiconductors in depth
  • Beginner who wants to start their career in electronics
  • Beginner who wants to perceive their career in VLSI domain

What you’ll learn: 

  • All the basic concepts of semiconductors
  • Semiconductors will help you understand how electronic devices like diodes, transistors, etc work
  • Concept of Energy, Valence and Conduction band diagrams
  • Understand the internal structure of diodes
  • Intrinsic and extrinsic semiconductors
  • Clears the basic concepts of electronic devices (EDC)


  • Should have basic idea about conductors
  • Basic idea of chemistry like atoms, shell, sub-shell, electrons, etc.

In this course, you will learn about semiconductors from scratch. Below, I had listed topics the course would cover. There are also topics not listed below but are covered because they are required to proceed further: 

  • Introduction to semiconductors
  • Difference between conductors, semiconductors, and an insulators
  • Energy band diagram for sodium and silicon atoms
  • Valence band and Conduction band diagram for sodium and silicon atoms
  • Forbidden Energy Gap
  • Intrinsic and Extrinsic Semiconductors
  • Internal structure or internal working of the p-n junction diode (Application part)

This is course 2 of a series and this course is a prerequisite to the next course which deals with diode circuits, Bjt, Fet’s circuits, etc. So, to understand the core electronics part or how any electronic device behaves, you should be very much well acquainted with the part of the semiconductor.

Our Promise to You

By the end of this course, you will have learned the basic concepts of semiconductors.
