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 better than silicon?
products made by silicon are more stable than those made by germanium
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.
Which is a better semiconductor silicon or germanium?
Silicon is generally considered a better semiconductor than germanium due to its higher melting point, wider operating temperature range, and superior thermal conductivity. Silicon is also more abundant and less prone to electrical leakage compared to germanium.
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 can metalloids can be made out of?
Metalloids are typically made out of elements that have properties intermediate between metals and nonmetals, such as silicon, boron, and germanium. These elements exhibit characteristics of both metals and nonmetals, making them important in various technological and industrial applications.

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.
What is a transister make of?
it is made of silicon or germanium.
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
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)
Are all metalloids man made?
No, metalloids are not all man-made. Metalloids are a group of elements on the periodic table that have properties of both metals and nonmetals. Some metalloids, like boron and silicon, are naturally occurring elements.
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.
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.
