Why germanium is better than silicon?

products made by silicon are more stable than those made by germanium


What are the metalloid elements on the periodic table?

Metalloid, or semi metal is a term used in chemistry when classifying the chemical elements. On the basis of their general physical and chemical properties, nearly every element in the periodic table can be termed either a metal or a nonmetal. However, a few elements with intermediate properties are referred to as metalloids. They are sometimes called (and confused with) semiconductors and semimetals.The following elements are generally considered metalloids:Boron (B)Silicon (Si)Germanium (Ge)Arsenic (As)Antimony (Sb)Tellurium (Te)Polonium (Po)Astatine (At)Inclusion of polonium is somewhat academic because all its isotopes are radioactive.


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.


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.


Which is a better semiconductor silicon or germanium?

silcon is a better semiconduter since,it has great applications like in making of nanowires which only can be made from silion.as, silicon is just after the carbon it exibit it's great property of catenation and can be made into tubes which can't be done with germanium so, in this way we can say that besides exibiting basic semiconducter properties silicon can show other useful properties too

Silicon


What type of material is a transitor made from?

germanium or silicon crystal


What is the definition of metalloid?

A Metalloid Is An Element Which Has Intermediate Properties Between Metals & Nonmetals ;)A product made of or to do with metal.A metalloid can have properties of both metals and nonmetals. Some examples of metalloids are Boron, Silicon, Germanium and Arsenic.


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)


Why is silicon the best example of a metalloid?

Silicon (Si) is one of seven elements that are known as the metalloids. This is just a fancy term to describe certain elements that don't behave exactly like metals or exactly like non-metals. The generally accepted list of metalloids is silicon, germanium, boron, arsenic, antimony, tellurium and polonium. Silicon can have properties like a metal or a non-metal depending on what other elements it combines with. Glass is a very common silicon compound that has non-metal qualities, while the silicon used in electronics can be made to act very much like a metal.


What kind of material is a transistor made from?

The class of materials that make up transistors is "semiconductor." A transistor is often made from very pure silicon that is doped with germanium or other dopant to change its electrical properties.


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.


Why silicon prefer to germiniuam?

Four reasons. First, it is a LOT cheaper and easier to get silicon. Germanium is a trace element in rocks. You need to mine and process lots of rock to get any germanium. Silicon is also known as sand--very easy to find. Second, germanium is heat sensitive. It's harder to solder a germanium device in than a silicon one because the heat can mess up the germanium. Germanium devices pretty much have to be soldered in by hand because you have to heat sink them, whereas silicon devices can be soldered in a soldering machine. Third, germanium's hazardous and silicon is generally not. People eat off glass plates, which are made from silicon. They do NOT eat from germanium plates, if they could even afford them. And fourth, germanium has a variable voltage drop--the higher the voltage, the greater the drop. If you pump 5000 volts into a silicon diode, you're going to get 4999.3v out the other side.
