What is the threshold voltage of silicon and germanium?
In semiconductor uses, such as diodes and transistors, the forward voltage drop for Silicon (Si) is a little less than 0.7 volts, while the FVD for Germanium (Ge) is about 0.3 volts.
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 are things made of germanium?
because of germanium oxide´s (GeO2) high refractive index, about 10% of worldwide germanium consumption is from optical uses such as lenses to cameras and centres of fibre cablesanother use of germanium is as a catalyst for polymerisation of polyethylene terephthalate, the plastic in most water bottles. germanium is also used in an alloy with silicon for semiconductors that can be faster then those with only silicon.
Why is germanium important?
Germanium is important because it is a semiconductor material used in electronics, such as transistors and diodes. It is also used in fiber-optic systems, infrared optics, and as a catalyst in certain chemical reactions. Additionally, germanium has potential applications in solar energy technology and as a health supplement.
What are the characteristics and uses of silicon and chlorine?
Silicon is widely used in semiconductors
Silicon uses in electronics?
Silicon is used in electronics as a semi-conductor. All of the processing units in computers now use silicon to keep parts from causing electrical signals from passing from part to part unless it is meant to. Silicon is also used in the making of transistors.
Describe some of the important properties and uses of silicon?
Properties: The melting point of silicon is 1410°C, boiling point is 2355°C, specific gravity is 2.33 (25°C), with a valence of 4. Crystalline silicon has a metallic grayish color. Silicon is relatively inert, but it is attacked by dilute alkali and by halogens. Silicon transmits over 95% of all infrared wavelengths (1.3-6.7 mm).Uses: Silicon is one of the most widely used elements. Silicon is important to plant and animal life. Diatoms extract silica from water to build their cell walls. Silica is found in plant ashes and in the human skeleton. Silicon is an important ingredient in steel. Silicon carbide is an important abrasive and is used in lasers to produce coherent light at 456.0 nm. Silicon doped with gallium, arsenic, boron, etc. is used to produce transistors, solar cells, rectifiers, and other important solid-state electronic devices. Silicones range from liquids to hard solids and have many useful properties, including use as adhesives, sealants, and insulators. Sand and clay are used to make building materials. Silica is used to make glass, which has many useful mechanical, electrical, optical, and thermal properties.
What are facts about germanium?
Germanium is an important semiconductor material used in transistors and various other electronic devices. Its major end uses are fiber-optic systems and infrared optics, but it is also used for polymerization catalysts, and in electronics and solar cell applications. It is finding a new use in nanowires.
What are some important uses of fermium?
Fermium hasn't uses.
