Silicon Germanium Gallium Arsenide (SiGeAs) is a semiconductor material that combines silicon, germanium, gallium, and arsenic. It is used in high-frequency applications due to its superior electron mobility.
Silicon Carbide (SiC) is a compound semiconductor made of silicon and carbon. It has excellent thermal conductivity and can operate at high temperatures, making it ideal for power electronics and high-temperature applications.

Why germanium is not used as LED material?
Germanium is not commonly used as an LED material because it has an indirect bandgap, making it less efficient for light emission. Materials with direct bandgaps, like gallium nitride and gallium arsenide, are better suited for LED applications as they allow for more efficient conversion of electrical energy into light.
What are silicon chips replaced of?
Silicon chips are typically made from semiconducting material, usually silicon, due to its abundance and ability to form the necessary structures. There are other materials with similar properties like germanium, indium arsenide, or gallium nitride that can also be used to create chips, but silicon remains the most widely used due to its cost-effectiveness and performance.
What is the common name of silicon carbide?
The common name of silicon carbide is carborundum.
What are semiconductors made of?
Semiconductors are typically made of materials such as silicon, germanium, or gallium arsenide. These materials have properties that allow them to conduct electricity under certain conditions, making them ideal for use in electronic devices like transistors and diodes.
What are the indirect bandgap materials?
Some examples of indirect bandgap materials include silicon, germanium, and gallium arsenide. These materials have a bandgap structure in which electrons have different momentum in the conduction band compared to the valence band, making optical transitions less likely.
Why germanium and silicon are not preferred in LEDs?
A: Because the element has different property as gallium arsenide.
What semiconductor material is used to make transistors?
* silicon * germanium * gallium arsenide * etc.
Why is LED not made of silicon or germanium?
Silicon and Germanium are not used to make LEDs.They are opaque to visible lightThey have the wrong type of band gap (direct instead of indirect).LEDs are made with binary semiconductors, like:Indium Gallium NitrideSilicon CarbideIndium PhosphideGallium Indium Arsenide NitrideIndium Gallium Aluminum Phosphideetc.
What is gallium arsenide supercomputer?
A supercomputer using gallium arsenide instead of silicon for its semiconductor components. Gallium arsenide is much faster than silicon so it helps significantly in getting the performance needed by a supercomputer, but it is much harder to fabricate resulting in an increase in price.
What has the author Richard Carl Eden written?
Richard Carl Eden has written: 'Photoemission studies of the electronic band structures of gallium arsenide, gallium phosphide, and silicon' -- subject(s): Silicon, Electrons, Gallium arsenide, Gallium Phosphide, Emission
The gallium arsenide is prepared for laser action but silicon and germanium are not. explain why?
I think because GaAs has a direct band gap transition but Si and Ge has indirect band gap transition. Both silicon and germanium are opaque and thus cannot be used to make LASERs.
How might a gallium chip compare with a germanium chip?
Gallium is a metal, not a semiconductor. You cannot build a transistor or even a diode with a piece of metal, forget an IC chip containing several transistors.To create a gallium based semiconductor, it must be ALLOYED with one or more of the following elements: nitrogen, phosphorus, arsenic, or antimony. The simplest semiconductor alloys are: gallium nitride, gallium phosphide, gallium arsenide, and gallium antimonide. Examples of other semiconductor alloys are: gallium nitride phosphide, gallium phosphide arsenide, etc. (these are used in some types of LEDs).The most common gallium alloy semiconductor for making transistors and IC chips is gallium arsenide. Compared to both silicon and germanium, transistors made of gallium arsenide are significantly faster, and additional speed can be obtained by using nonsaturating logic circuits like ECL.
Power diode made up of?
Power diodes are made primarily of silicon, though small quantities of other materials, such as boron, gallium arsenide, germanium or phosphorous are also used.
Why germanium is not used as LED material?
Germanium is not commonly used as an LED material because it has an indirect bandgap, making it less efficient for light emission. Materials with direct bandgaps, like gallium nitride and gallium arsenide, are better suited for LED applications as they allow for more efficient conversion of electrical energy into light.
Are silicon bismuth antimony gallium germanium elements or substances?
both
What metal is a semi conductor?
The most commonly used metal as a semiconductor is silicon. Other metals that can be used as semiconductors include germanium and gallium arsenide. These materials have unique electronic properties that make them useful in electronic devices like transistors and diodes.
What is an integrated circuit chip made from?
Mostly silicon but other compounds such as gallium arsenide are also used.
