What is the meaning of semiconductors?
Oversimplifying it significantly "not quite conductors". These are materials whose ability to conduct electricity is between conductors and insulators but can be very precisely controlled by doping with other elements as impurities, allowing the construction of electronic devices that can: control the direction of current flow, amplify signals, act as switches, perform boolean logic functions, etc. These materials can be classed as elemental semiconductors, binary semiconductors, other semiconductors. The elemental semiconductors are elements with 4 valence electrons that are not metals (e.g. silicon, germanium), the binary semiconductors are "alloys" of two elements: one with 3 valence electrons and the other with 5 valence electrons (e.g. gallium arsenide, indium phosphide), other semiconductors can be elements (e.g. selenium) compounds (e.g. galena, copper oxide) or complex "alloys" of several elements (e.g. gallium arsenide phosphide, aluminum gallium indium phosphide). The term semiconductors is also used to refer to the electronic devices mades of these materials.
What is semiconductor die?
it refers to a grow silicon seed that is used to grow the final semiconductors
What types of elements are used as semiconductors?
Most semiconductors are elements with 4 valence electrons:carbon as either diamond or nanotubes, still has process problemssilicon, most preferred nowgermaniumThere are also binary semiconductors made of alloys of elements with 3 & 5 valence electrons:gallium arsenide is used in some very high speed electronicsaluminum indium gallium phosphide is used in some LEDs and solid state LASERsetc.There are also less commonly used semiconductors used in special purpose applications:copper oxide used to be used in high voltage rectifiers in low cost vacuum tube electronicsselenium is used in light sensitive drum in photocopiers and laserprinterslead sulfide (galena) used in crystal radiosetc.
What is a semiconductor used for?
Semiconductors may be used to fabricate electronic devices. This is done quite often. Most of the electronic devices they're used for are called "transistors". Often, several transistors are combined in a single small device, called an "integrated circuit". A few examples of where these devices may be found in real life include . . . -- almost every radio in the world -- almost every TV set in the world -- almost every landline telephone in the world -- every TV remote -- every GPS -- every CD/DVD player -- every cellphone and every smartphone in the world.
Can you explain why silicon and germanium are used in the manufacturing of semiconductors?
silicon is less sensitive towards temperature.It costs low compared to germanium,
What elements are used in computers because they have properties of both metals and non metals?
Metalloids, such as silicon and germanium, are used in computers because they have properties of both metals and nonmetals. They can conduct electricity like metals, but also have some properties of nonmetals, making them ideal for use in semiconductors and other electronic components.
Are non metals semiconductors?
Metals are conductors. Semiconductors are usually non-metals or metalloids.
How does the number of valence electrons in atoms of metalloids explain why metalloids are semiconductors?
Metalloids when used is electronics are called semiconductors.
What metals and non metals are used in computers and electronic devices?
Metals commonly used in computers and electronic devices include copper (wiring), gold (connectors), aluminum (heat sinks), and iron (steel casing). Non-metals like silicon (semiconductors), carbon (plastic components), and oxygen (used in insulating materials) are also essential in electronic devices.
Is it possible to make electrical gadgets without the help of element?
Electrical gadgets often contain hydrogen- not in the electrical components themselves but in the plastics used for example in insulators and structural components. The electrical components contain conducting meterials such a s metals and for elctronic devices semiconductors.
Why are tin and lead not used as semiconductor?
because they are not semiconductors. They are metals and rather good conductors.
Which type elements are used as semiconductors?
Metalloids. They are squeezed between metals and non-metals in the periodic table. They include silicon and germanium.
What properties of semiconductors make them useful in electric devices?
They can be used as a base material for computer chips
What is the purpose of semiconductors?
Semiconductors are the materials that has conductivity higher than the insulator but lower than the metals. Can be used in various purpose i.e., LED, LASER also fabricating various ICs etc.
Do metalloids have characteristics of both metals and nonmetals?
Yes, metalloids have properties that sit between metals and nonmetals. They can conduct electricity to some extent like metals, but can also behave as insulators in some conditions like nonmetals. They also have intermediate physical properties such as luster and conductivity.
What is the connection between a metalloid and semiconductor?
The connection between a metalloid and a semiconductor is that metalloids are used in electronics as semiconductors. A semiconductor doesn't conduct electricity as well as a metal, but does conduct electricity better than a nonmetal.
Why are metalloids used in the electronic goods industry?
Metalloids such as silicon and germanium are used in the electronic goods industry because they exhibit properties of both metals and nonmetals. They are semiconductors, which means they can conduct electricity under certain conditions. This property is essential for the fabrication of electronic components like transistors and diodes.
