. the basic difference between these two are their doping level, holes, and electrons quantity define their differences.
Here we will cover all details about these materials. So let get started.
Difference Between Intrinsic and Extrinsic Semiconductor
What is Extrinsic Semiconductor
- These semiconductors are created if the impurity is added in the intrinsic semiconductors. That is called doped or impurity semiconductor
- Semiconductors are such material that has conductivity among the conductor and insulator called amorphous solids.
- The addition of doped or impurity material enhances its electric features and is used in different electronic devices such as transistors and diodes
- Doping is a technique through which bandgap is regulated through the addition of impurity substances.
- The addition of other materials to a semiconductor enhances its conductance multiple times the added material called dopants
- The impurity material added depends on the final semiconductors obtained.
- A decent extrinsic semiconductor can be created by adding a small amount of impurity.
- Before adding the impurity make sure that the dopant has the same size to the original atom also dopants not disturb the structure of the original atom
Types of Dopants in Extrinsic Semiconductors
- Doping results to vary the conduction in semiconductors. The component of 4th group of the periodic table such as silicon and germanium known as semiconductors this two materials have tetravalent crystals so used for 2 categories of dopants
- P-type semiconductor
- N-type semiconductor
- A diode is semiconductor device that used in circuits as rectifiers
- P and N materials combine to make the PN junction
- These devices are used in FET and BJT.
- It used as switches
- Doping does not vary the net neutrality of component
- Electrons are the majority in N semiconductors and holes in P semiconductors
What is Intrinsic Semiconductor
- The semiconductor that are not doped called intrinsic or pure semiconductors. The charger carries is finds through finding the features of material in place of impurity added like extrinsic material
- These materials have the same electrons and holes.
- The conduction of material can be affected through crystallographic causes of technology
- In this material such as silicon over the temperature value larger than the absolute zero get energy and move from the excitation to the conduction band that resulting in current
- When electrons change the band holes is created at their place. Due to external forces applied by the volts electrons and hoes moves in the substances.
- In case of N material impurity gives additional electrons that enhance the conductivity
- In case of P-type material dopant generates addition holes also increase the conduction,
What is Semocinductior Current
- The current flowing in the intrinsic material is caused by both holes and electron current.
- Electrons that are released from the conducts in the conduction band can move in the substances.
- In a result, other electrons come to full the position created by the released electrons
- This process is known as hole conduction since it is created as if holes are moving in the substance against the direction of electrons.
- The current flowing these materials is affected by the energy states that has an impact on the quantity of the electrons in the conduction band, SO can say that this current totally relies on the temperature
That is all about the Difference Between Intrinsic and Extrinsic Semiconductor. all details has been explained. If you have any further queries ask in comments. Thanks for reading have a nice day.

Hello readers welcome to the new tutorial. Here we will discuss PCB Design with EasyEDA & JLCPCB. PCB is a very basic part of any electronic project so it needed certain demands and precautions for the creation of it and making its design. There are different ways that are used for the creation of the board here I will tell you basic and simple way through EasyEDA PCB design. After that will tell you how you can get the PCB after making design from JLCPCB which is the best PCB supplier in the world.
JLCPCB and EasyEDA belong to one big group or say they are sister companies. Meanwhile, designers can place their PCB order directly via EasyEDA after getting the design done.. To make the PCB design we will use a simple circuit of the project and make its design on the PCB board. So let get started all steps used for designing the PCB board. Before it you must have idea about JLCPCB from that you will get the board after creating the design. It was Founded in 2006, and JLCPCB has been at the forefront of the PCB industry. With over 15-year continuous innovation and improvement based on customers’ needs, they have been growing fast, and becoming a leading global PCB manufacturer, that provides the rapid production of high-reliability and cost-effective PCBs and creates the best customer experience in the industry. So let get started
PCB Design with EasyEDA & JLCPCB
- To design PCB board through EasyEDA and also I am using it to make the design.
- First of all you have an account on the EasyEDA site for this purpose type EasyEDA in google and visit their site.
- If you new user of EasyEDA press on the register button shown below
- When you press on the register button new interface will open here put all details and press sign up button then verification email will you get on your email press on it and activate your account.
- Move to EasyEDA site then log to your account after that press on EasyEDA designer tab then new projects tab will seen press on it and write the name of your project then save it.
- new interface will be shown can be seen here
- Before making the project will have some understanding of the EasyEDA software tools and functions.
- First one is project option where you can see all details of projects that you have made in the software.
- Next is design manager where we can see details of all components used in our projects and wire used for making connections.
- Next component library where all components for the project can get to make a circuit diagram. Any project you can create from components get from this library
- After that know about the menus of software
- First one is file tab from where you can create new or already made projects. With other features that are listed in the figure
- Another one is the place tool that has wire, bus and different often used for projects.
- The design tool will use for the conversion of the schematic to PCB.
- In below figure the details of objects elected in the circuit can seen.
- Till now I hope you have get the detail overview of EasyEDA software that will help you to make the design. Now we will draw the circuit of our project that we are using for PCB design. The CIrcuit can be seen here
- The component that we will use in the circuit are listed here
- capacitor 5 in number
- Resistances 4 in numbers
- Speaker as load
- All values of these components can be seen in the above figure
- Al these components of circuits are get from the component library can seen in the below figure.
- After that, all components connect according to the project’s circuit diagram and their respective value changes according to requirements.
- Now move to design tab and press on the convert schematic to PCB new interface will be displayed.
- In the below figure you can see the PCB tools tab that will used to design the PCB. In the PCB layer window we can hide and unhide any layer also layer can be edit from here
