In what way is germanium similar to silicon?
Germanium and silicon are both in the same group of the periodic table (Group 14) and share similar electronic properties. They are both commonly used in semiconductor technology and have similar crystal structures, making them suitable for use in electronics devices such as transistors and diodes.
Why silicon and germanium called as semiconductor?
Silicon and germanium are called semiconductors because they have an electrical conductivity between that of a conductor and an insulator. At room temperature, these materials have a moderate number of charge carriers, allowing them to conduct electricity under certain conditions. This property makes them ideal for use in electronic devices.
Why we don't we use iron as a semiconductor?
Iron is not typically used as a semiconductor because its electronic properties make it better suited as a conductor. Additionally, iron's crystalline structure does not easily allow for the manipulation of its electrical conductivity to the extent required for use as a semiconductor in electronic devices. Other materials such as silicon and gallium arsenide are more commonly used for semiconductors due to their superior electronic properties.
Why you use germanium crystal?
Germanium crystal is used in certain electronics applications, such as transistors and diodes, due to its unique semiconducting properties. It has a high charge carrier mobility and is sensitive to infrared light, making it useful in infrared optics and sensors. Additionally, germanium is compatible with silicon-based technologies, allowing for integration into existing semiconductor processes.
Why is silicon and germanium used in semiconductors.pdf?
Silicon and germanium are used in semiconductors because of their unique electronic properties, specifically their ability to conduct electricity under certain conditions. They have a crystalline structure that allows them to be easily doped with impurities to control their electrical behavior, making them ideal for use in the fabrication of electronic devices such as transistors and diodes. Additionally, Silicon is the most abundant element on Earth after Oxygen, which makes it cost-effective for large-scale production of semiconductor devices.
Was Germanium used in transistors?
Yes, germanium was the only material used in transistors from when they were invented in 1947 until 1954 when the first successful silicon transistor was made. However the use of germanium still dominated transistors until the silicon mesa transistor was made commercially available by Fairchild Semiconductor in 1958. Development of the silicon planar transistor by Fairchild Semiconductor the next year ultimately made the integrated circuit possible. While almost all transistors today are silicon, there are still uses for germanium transistors so a few types are still made.
What does a semiconductor have to do with a computer?
some first generation computers used germanium point contact diodes in their logic gates to reduce their vacuum tube parts count.second generation computers used discrete germanium or silicon transistors.third generation and later computers use silicon integrated circuits.
In what way is germanium similar to silicon?
Germanium and silicon are both in the same group of the periodic table (Group 14) and share similar electronic properties. They are both commonly used in semiconductor technology and have similar crystal structures, making them suitable for use in electronics devices such as transistors and diodes.
A semiconductor can be made by adding atoms of other elements to?
A semiconductor can be made by adding atoms of other elements to a pure semiconductor material, such as silicon or germanium. By selectively adding specific impurity atoms (dopants), the conductivity of the semiconductor material can be controlled, making it suitable for use in electronic devices like transistors and diodes.
Is germanium conducts electricity?
Germanium is a metal that conducts electricity and germanium crystals can be prepared in a manner allowing them to conduct electrify through their crystal lattice is one direction only, making germanium crystals valuable for use in transistors and rectifiers.
Why is pure silicon chemically classified as a semiconductor?
because silicon and germanium can use as a both type of material conductor or insulator they found in nature as a non conducting element but we can turn them in to conductor by mixing some impurities and that process is known as damping.
Why silicon and germanium called as semiconductor?
Silicon and germanium are called semiconductors because they have an electrical conductivity between that of a conductor and an insulator. At room temperature, these materials have a moderate number of charge carriers, allowing them to conduct electricity under certain conditions. This property makes them ideal for use in electronic devices.
Why is silicon is preferred is germanium?
Silicon is actually preferred to germanium within the manufacture of semiconductor devices due to the following reasons:Silicon is cheap and abundantIn silicon, leakage current is less affected by temperature as compared to germanium.The leakage current in silicon is very very small as compared to germanium.The working temperature of silicon is more than that of germanium. The working junction temperature of silicon can go as high as 150C whereas the working junction temperature of germanium can only go as high as 60CSilicon dioxide is a stable insoluble solid that can be used both to electrically insulate circuitry and to passivate junctions preventing contamination (allowing use of inexpensive plastic packages), germanium dioxide is a crumbly water soluble solid (this requires all germanium devices to be packaged in expensive metal or glass hermetically sealed cases and making germanium integrated circuits almost impossible)
Why you use silicon not germanium in SCR?
because lekage current of silicon is less than germenium

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)
