Silicon and Germanium are not used to make LEDs.
- They are opaque to visible light
- They have the wrong type of band gap (direct instead of indirect).
LEDs are made with binary semiconductors, like:
- Indium Gallium Nitride
- Silicon Carbide
- Indium Phosphide
- Gallium Indium Arsenide Nitride
- Indium Gallium Aluminum Phosphide
- etc.
What else can I help you with?
What is a transister make of?
it is made of silicon or germanium.
Why germanium is not used as LED material?
LEDs are made from binary semiconductors (e.g. gallium aluminum indium phosphide) not unary semiconductors (e.g. silicon, germanium) because they can be made transparent to light. Silicon & germanium are opaque.
Why germanium is better than silicon?
products made by silicon are more stable than those made by germanium
What type of material is a transitor made from?
germanium or silicon crystal
Diodes and transistors are made of semiconductor material such as germanium and what?
Silicon
Where is germanium and silicon located in computer chips?
Germanium is not used in integrated circuits. Silicon is.
Why don't use germanium in silicon controlled rectifier?
the leakage current of silicon is less when compared with the leakage current of germanium.. hence scr's are made up of silicon than germanium.. hope tis one is useful to u all!- Vignesh.L(engineer, 1st year)
What element is used in making transistors and chips?
Silicon and Germanium are the elements used in transistors
The modern name for eka-silicon?
germanium
What has more shells or rings germanium or silicon?
germanium
Is silicon a semiconductor?
Yes,silicon and germanium are semiconductors.
What is silicon germanium Gallium Arsenide and silicon Carbide?
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.
