in silicon or germanium, the valence shell contain 4 electrons. in order to attain stability,
they need 4 more electrons, so we doping it either with trivalent or pentavalent
impurities. if we are doping semiconductor with any of these, we call it as an extrinsic
semiconductor if we are using pentavalent impurity such as phosphorous, there will be an
extra electron,which will go to conduction band. we know electron has negative charge
therefore we call it as n-type semiconductor
Germanium is an element that exhibits similar behavior to silicon and lead. It shares some properties with silicon, such as being a semiconductor, and also shares some properties with lead, such as being a metalloid.
Germanium is an unusual non-metal element found at the top of the group in the periodic table that also includes silicon. Germanium shares similar properties with silicon and is commonly used in semiconductors and electronic devices.
What type of element is phosphorus
If phosphorous occupie the gallium sites, it would be n type semiconductor since it has more number of valence electrons than gallium and if it occupie the sites of the arsenic sites there is no change since the valency of arsenic and phosphorous be the same
Phosphorus is not a mixture; it is an element on the periodic table with the symbol P and atomic number 15. It exists in various forms, such as white phosphorus and red phosphorus, but each form is composed of only phosphorus atoms.
The 32nd element on the periodic table is Germanium (Ge). It is a metalloid with properties that make it useful in semiconductor applications.
Germanium is not explosive. It is a chemical element with a low reactivity and has no explosive properties. It is commonly used in electronic devices and as a semiconductor in transistors.
Germanium is a solid at room temperature and is a nonmetal and the call name is (Ge)
An n-type semiconductor is formed by doping a pure semiconductor (silicon or germanium, for example) with atoms of a Group V element, typically phosphorus or arsenic. The dopant may be introduced when the crystal is formed or later, by diffusion or ion implantation.
Germanium is classified as a metalloid, a type of element that has characteristics of both metals and non-metals. It is located in Group 14 of the periodic table, along with elements like carbon and silicon. Germanium is used in semiconductor technology and infrared optics.
A geranium is a flower, and not a semiconductor. The element Germanium, however, is a semiconductor, which means it has an electrical conductivity somewhere between that of a metal and an insulator.
Intrinsic semiconductivity
No, mercury is not a semiconductor. It is a metallic element that is a liquid at room temperature. Semiconductor materials are distinct from metallic elements like mercury and include materials like silicon and germanium.
Germanium is a metalloid, which is an element that shares properties of both metals and nonmetals. It has characteristics of both categories, such as being a semiconductor like a nonmetal but also having metallic luster.
Germanium is a metalloid element with the atomic number 32 on the periodic table. It is commonly used in the production of semiconductor materials for electronic devices. Germanium was used in early transistors and is still found in some infrared optical equipment today.
The discovery of germanium was important because it filled a gap in the periodic table, demonstrating the usefulness of Mendeleev's periodic law. Germanium's properties as a semiconductor also made it a crucial element for the development of early electronic devices like transistors, paving the way for modern technology.
An element that has properties of both metals and non-metals is called Metalloid. Example is Germanium.
