As per theory of semiconductor, impure semiconductors are called extrinsic semiconductors. Extrinsic semiconductor is formed by adding a small amount of impurity. Depending on the type of impurity added we have two types of semiconductors: N-type and P-type semiconductors.In 100 million parts of semiconductor one part of impurity is added.

Jan 31, 2011 · Semiconductor Theory. 12. Creating a Diode When you connect electrically N-type and P-type silicon as shown below, you find that the following happens and this produces a useful effect. p type n type Negative Positive The electrons in the N-type will move across the junction to recombine with the holes in the P-type. P-Type Materials The p-type material is formed by doping a pure germanium or silicon crystal with impurity atoms having three valence electrons. The elements most frequently used for this purpose are boron, gallium, and indium. The diffused impurities with three valence electrons are called acceptor atoms. Note that there is now an insufficient number of electrons to complete the covalent.

PDF Quantum Electronics in Semiconductors.
Semiconductors Solids can be classified as metals, semiconductors or insulators based on conductivity or resistivity and energy bands in electronics. This helps us understand the band theory and the importance of valence and conduction bands in solids. Let us also study the types of semiconductor. Classification Based on Conductivity. 3. Basic Semiconductor Physics [4] [2] [6] A semiconductor is a solid whose electrical conductivity is in between that of a metal and that of an insulator, and can be controlled over a wide range, either permanently or dynamically. Semiconductors are tremendously important technologically and 1 Diodes are really not used in digital circuits. The goal of this text, as its name implies, is to allow the reader to become proficient in the analysis and design of circuits utilizing discrete semiconductor devices. It progresses from basic diodes through bipolar and field effect transistors.
