Solution
semiconductors which are made up of pure silicon or germanium without any impurities are called Intrinsic semiconductors. Semiconductors which are doped with some kind of impurity to improve their fuctioning or conductivity or resistivity etc are called extrinsic semiconductors.
There are two types of semiconductors which are
1) p-type semiconductors - in these types of semiconductors the doping material which is used is a trivalent substance. In a normal Si/Ge semiconductors, these are tetravalent which means these contains four electrons in their outermost shell and when a trivalent substance replaces a Si/Ge atom in the crystal it creates a HOLES, these show the lack of electron or can be realted to positive charge. Thats why such semiconductrs are known as p-type semiconductrs. The trivalent substance which is doped must belong to the III group, for example Aluminium( Al ), indium( In ) etc.
2) n-type semiconductors - in these types of semiconductors the doping material which is used is a pentavalent substance. In a normal Si/Ge semiconductors, these are tetravalent which means these contains four electrons in their outermost shell and when a trivalent substance replaces a Si/Ge atom in the crystal, so there will be an extra electron, these show the lack of electron or can be realted to positive charge. Thats why such semiconductrs are known as n-type semiconductrs. The pentavalent substance which is doped must belong to the V group, for example phosphorous( P ), arsenic ( As )etc

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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

3. Types Of Semiconductors
There are two types of semiconductors
1) Intrinsic Semiconductors
2) Extrinsic Semiconductors
Intrinsic Semiconductors
Ex: si,Ge etc
Extrinsic semiconductors
Ex: p-type and n-type
4. Doping Process
Doping process is a process of adding some impurities in
Intrinsic semiconductors.
Dopant
The impurity used in doping process is called as dopant.
There are two types of impurities
1) Donor Impurity : Arsenic,phosphorous,Antimony,etc.
2) Acceptor Impurity: Gallium,Aluminium,etc.
5. N-Type Semiconductors
It is a process of adding a small amount of
Pentavalent impurity(donor) impurity in pure
Semiconductor.
Pentavalent impurity such as arsenic added
In Intrinsic semiconductor to create four covalent
bond with
Fifth electron of arsenic is free on material.
In N-Type material majority carries electrons and
minority carries wholes are present.
6. P-Types Semiconductors
It is a process of adding small amount
Of trivalent impurity(acceptor) impurity
In pure semiconductor.
Boron create three covalent bond with
Nearest atom and one covalent bond
Is broken due to no electrons free in
Outermost cell.
In P-Type material majority carries electrons
and minority carries wholes are present
