This document discusses semiconductors and diodes. It defines conductors, insulators, and semiconductors based on their electrical properties. Semiconductors can be intrinsic or extrinsic depending on whether they contain dopant impurities. Extrinsic semiconductors are classified as N-type or P-type based on whether electrons or holes are the majority carriers. A diode is formed from a P-N junction where a P-type and N-type semiconductor meet. Diodes only allow current to flow in one direction and have unique voltage-current characteristics depending on whether they are forward or reverse biased.

Semiconductors
Introduction
Semiconductor is a solid substance that has conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.
Examples: Silicon, Germanium, Carbon
Intrinsic & Extrinsic Semiconductor
Semiconductors are mainly classified into two categories: Intrinsic and Extrinsic. An intrinsic semiconductor material is chemically very pure and possesses poor conductivity. It has equal numbers of negative carriers (electrons) and positive carriers (holes). Where as an extrinsic semiconductor is an improved intrinsic semiconductor with a small amount of impurities added.
The Doping of Semiconductors
The addition of a small percentage of foreign atoms in the regular crystal lattice of silicon or germanium produces dramatic changes in their electrical properties, producing n-type and p-type semiconductors.
Pentavalent impurities
Impurity atoms with 5 valence electrons produce n-type semiconductors by contributing extra electrons.
Trivalent impurities
Impurity atoms with 3 valence electrons produce p-type semiconductors by producing a "hole" or electron deficiency.
N-Type Semiconductor
The addition of pentavalent impurities such as antimony, arsenic or phosphorous contributes free electrons, greatly increasing the conductivity of the intrinsic semiconductor. Phosphorous may be added by diffusion of phosphine gas (PH3).
P-Type Semiconductor
The addition of trivalent impurities such as boron, aluminum or gallium to an intrinsic semiconductor creates deficiencies of valence electrons,called "holes". It is typical to use B2H6 diborane gas to diffuse boron into the silicon material.
Diodes
A device that blocks current in one direction while letting current flow in another direction is called a diode. Diodes can be used in a number of ways. For example, a device that uses batteries often contains a diode that protects the device if you insert the batteries backward. The diode simply blocks any current from leaving the battery if it is reversed -- this protects the sensitive electronics in the device.
Semiconductor devices
Introduction to Semiconductor Devices.
In modern world no other technology permeates every nook and cranny of our existence as does electronics.
Application of electronics are : Televisions, radios, stereo equipment, computers, scanners, electronic control systems (in cars for example) etc.
Semi conductor
Semiconductors are materials with electrical properties between conductors and insulators. Doping semiconductors with impurities creates either excess electrons (N-type) or holes (P-type). Diodes are formed by joining a P-type and N-type semiconductor, creating a PN junction. Current flows easily through the diode in one direction under forward bias but is blocked under reverse bias, allowing rectification of alternating current into direct current.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
How to Setup Warehouse & Location in Odoo 17 Inventory
In this slide, we'll explore how to set up warehouses and locations in Odoo 17 Inventory. This will help us manage our stock effectively, track inventory levels, and streamline warehouse operations.
Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

Walmart Business+ and Spark Good for Nonprofits.pdf
"Learn about all the ways Walmart supports nonprofit organizations.
You will hear from Liz Willett, the Head of Nonprofits, and hear about what Walmart is doing to help nonprofits, including Walmart Business and Spark Good. Walmart Business+ is a new offer for nonprofits that offers discounts and also streamlines nonprofits order and expense tracking, saving time and money.
The webinar may also give some examples on how nonprofits can best leverage Walmart Business+.
The event will cover the following::
Walmart Business + (https://business.walmart.com/plus) is a new shopping experience for nonprofits, schools, and local business customers that connects an exclusive online shopping experience to stores. Benefits include free delivery and shipping, a 'Spend Analytics” feature, special discounts, deals and tax-exempt shopping.
Special TechSoup offer for a free 180 days membership, and up to $150 in discounts on eligible orders.
Spark Good (walmart.com/sparkgood) is a charitable platform that enables nonprofits to receive donations directly from customers and associates.
Answers about how you can do more with Walmart!"

- 1. SEMI CONDUCTORS Name:-P.Venkata Ganesh Reddy Reg;-PROV/B.TECH-8-22/470
- 2. Conductors In general all conductors.Are good conductors The purpose of conductors is to allow electrical current to flow with minimum resistance. Examples: Copper, gold, silver, iron,bronze
- 3. Insulators Insulators are used to prevent the flow of electricity. Insulating materials such as glass, rubber, plastic, polyethylene are also called dielectrics, meaning they can store charges Dielectric materials are used in components like capacitors which must store electric charges
- 4. Semiconductors are materials whose electrical properties lie between Conductors and Insulators. EX:- Silicon Germanium Introduction
- 6. Intrinsic & Extrinsic Semiconductor Semiconductors that are free of doping impurities are called intrinsic semiconductors. Semiconductors formed after adding impurities are called extrinsic semiconductors. Two types of extrinsic (impure)semiconductors, N-type P-type
- 8. DOPING PROCESS Doping is a process of adding a certain amount of specific impurities called dopants to a pure semiconductor to increase its electricity conductivity.
- 9. What P-type and N-type? Semiconductors are classified in to P-type and N-type semiconductor P-type: A P-type material is one in which holes are majority carriers i.e. they are positively charged materials (++++) N-type: A N-type material is one in which electrons are majority charge carriers i.e. they are negatively charged materials (-----)
- 11. Diodes It is represented by the following symbol, where the arrow indicates the direction of positive current flow.
- 12. What is the p-n junction? A p-n junction is formed when a n-type and p-type semiconductors are joined together. The boundary between the p-type and n-type regions is called the junction. At the p-n junction, electrons from the n-side move to the p-side and recombine with the holes. Holes from the p-side similarly move into the n side, where they recombine with electrons. As a result of this flow, the n-side has a net positive charge, and the p-side has a net negative charge.
- 13. Characteristics of Diode Diodes alwayDiode always conducts in one direction. s conduct current when "Forward Biased" (Zero resistance) Diodes do not conduct when Reverse Biased (Infinite resistance)
- 14. I-V characteristics of Ideal diode
- 15. -V Characteristics of Practical Diode Volt-ampere characteristic for a typical small-signal silicon diode at a temperature of 300 K. Notice the change of scale. for negative current and voltage.
