Test Preparation

In the lesson we discuss the models of atom given by rutherford and neils bohr .

The Nature Of Atom

in this lesson we dicuss the formation of energy bands and classification of materials on the basis of energy gap .also we discuss the types of semiconductors .

Energy Band Theory

Here we dicuss lorentz force , derivation of hall voltage and how hall effect is used to find the type of demiconductor .

Hall Effect

In this lesson we discuss concept of mobility and parameters which affect it . drift and diffusion current density are also explained .

Mobility and Conductivity

In this lesson we discuss the electric field , potential , potential energy and kintetic energy and the potential energy barrier for electrons anf holes .

Potential Energy Barrier

In this lesson we derive the law of junctions and discuss process of recombination .

Law of junctions

In this lesson we discuss shift in fermi level due to doping and temperature . doping with both acceptor and donor impurities and degenerative doping is also covered .

Shift in fermi level

In this lesson we discuss intrinsic and extrinsic semiconductors and their formation .

Intrinsic semiconductors and doping 1

Intrinsic semiconductors and doping 2

In this lesson we calculate the concentration of electrons and holes in extrinsic semiconductor and determine the position of fermi level in p-type and n-type semiconductors .

Fermi level in extrinsic semiconductors

In this lesson we derive electron and hole conentration using the fermi dirac probability function .

Fermi dirac distribution 1

In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either lossy or lossless. This course is about various compression techniques, and related algorithms.

Data Compression Techniques and its Algorithm
