This lesson presents to you a brief description of the topics that are covered in the course. It also describes the summary of important points which will be helpful in your preparation for the examination.

Overview of the Course (in Hindi)

In this lesson, we will learn about some basic concepts regarding semiconductor physics. It introduces you to the very foundation tools which one needs to master before he can move further in the course.

Introduction to Semiconductor Physics (in Hindi)

The lesson deals with the concepts of band structure, material classification. It will also deal with the thermal voltage to give you a clear understanding of the circuits.

Basics of Semiconductor Physics (in Hindi)

In this lesson we will study about, types of semiconductor, temperature coefficient. The lesson deals with the concept of mobility, its variations with respect to temperature and electric field. At the end, we will study about a variation of drift velocity and electric field and plot a curve between them.

Types of Semiconductor and Basic Concepts (in Hindi)

In this lesson, we will learn about the various currents like drift, diffusion, etc. It also deals with the concepts of the law of mass action, explained to you for the preparation of teh examination.

Drift, Diffusion, Law of Mass Action (in Hindi)

In this lesson, the concept of fermi energy level, charge neutrality principle, conductivity and resistivity will be discussed. We will also study about temperature dependence,  the position of fermi level in the n-type, p-type and intrinsic semiconductor. We will be able to calculate conductivity and resistivity of n type and p type semiconductor.

Fermi Energy Level, Conductivity, Resistivity (in Hindi)

We will learn about working of diode and importance of biasing. The lesson deals with the types of biasing, characteristics of the diode.It will also include the concept of diode capacitance. ie transition capacitance and diffusion capacitance and their concerned formulas.

Working of Diodes (in Hindi)

We will learn about bipolar junction transistor and its working, its symbol, types, and characteristics. we will also analyze early effect, change in the current gain of a transistor due to early effect, punch through in a transistor and other concepts.
