because we have hall cofficient =1/ne. where the n=no of electron ,e=charge of electron. we know that "n "in metal is very large. so that R=HALL COFFICIENT" is very small FOR it .so we can not find sufficient result for hall cofficient so we use semi conductor which gives non zero hall cofficient.
No, germanium is a semiconductor material, not an insulator. It has electrical properties that are in between conductors (like metals) and insulators (like nonmetals), making it useful for various electronic applications.
Germanium is a semiconductor, meaning it can conduct electricity under certain conditions. It does not conduct electricity as well as metals like copper or silver, but it is commonly used in electronic devices and transistors.
No, boron is not likely to be an insulator. It is a metalloid with properties that are in between those of metals and nonmetals, so its conductivity can vary. Pure boron tends to behave more like a semiconductor rather than an insulator.
Yes, germanium does conduct heat. It is a semiconductor material that can conduct both heat and electricity, although not as efficiently as metals. Germanium is commonly used in electronics and thermal imaging devices due to its ability to conduct heat.
Germanium is a semiconductor, it means that electrons are relatively strongly attached to nuclei. As result its thermal properties change. Generally semiconductors have worse thermoconductivity than metals but better than insulators.
Yes, silicon is a metalloid. It exhibits properties of both metals and non-metals, such as being a semiconductor and having a shiny appearance. This positions it between metals and non-metals on the periodic table.
An alloy is a mixture of two metals
reactivity
An element could be a metal.
The connection between a metalloid and a semiconductor is that metalloids are used in electronics as semiconductors. A semiconductor doesn't conduct electricity as well as a metal, but does conduct electricity better than a nonmetal.
One is hard one is soft
One key physical difference between transition metals and poor metals is that transition metals have high melting and boiling points compared to poor metals. Transition metals also tend to be more malleable and ductile, while poor metals are typically softer and have lower melting points.
Metals generally are good conductors of electricity, and nonmetals are not.
Semiconductor is not a single substance and so cannot be identified as either. Many semiconductors are made with metalloids, which have properties of both metals and nonmetals
Scientists classify silicon as a metalloid, which is an element that exhibits properties of both metals and non-metals.
semiconductor elements. You may want to confirm this on a science website. GOOD LUCK!
