The semi conductors like Si, Ga, Ge are purified by Zone refining. it is also known as fractional crystallisation method.It works according to the principle that when an impure metal is melted and allowed to solidify, the impurity move away from the solid region and prefer to be distributed in the molten region.
Semiconductor compounds are typically purified through techniques like zone refining, chemical vapor deposition, or molecular beam epitaxy. These methods involve processes such as heating the compound to high temperatures to evaporate impurities, or depositing a thin, pure layer of the compound onto a substrate. The end goal is to remove impurities and ensure a high level of purity for optimal semiconductor performance.

Is sodium a semi conductor?
No, sodium is a metal and is not a semiconductor. Semiconductors are materials that have conductivity between that of a conductor and an insulator. Sodium is a good conductor of electricity due to its metallic properties.
What is silver a conductor insulator or semi-conductor?
Silver is a conductor of electricity. It has low resistivity, allowing electric current to flow easily through it compared to insulators like rubber or semi-conductors like silicon.
Is a purified bottle water a compound?
Purified bottled water is not a compound, as it consists of a single substance: water. Water is a compound made of two elements, hydrogen and oxygen, chemically bonded together.
Is silver a conductor a semi-conductor or a insulator?
Silver is a conductor of electricity, meaning it allows the flow of electric current with very little resistance. It is widely used in electrical wiring and electronics for this reason.
Is it found in a compound or in pure from?
It can be found in both compound and pure forms. In nature, elements are often found in compounds, while in labs, they can be isolated and purified into their elemental form.
How can you increase the conductivity of a semi conductor?
The conductivity of a semi-conductor can be increased by raising the temperature of the semi-conductor .
Is copper a conductor insulator or semi conductor?
Copper is a conductor.
What are example of semi conductor?
Germanium and Silicon are the two most commonly known semi-conductor materials
Which one is used in the laser printing wheather dye laser or semi conductor laser?
semi-conductor
Is silver and gold such as jewelry, are they great semi conductor?
Yes, silver and gold are good semi conductor.
What are semi insulators?
A semi conductor is not a good conductor or a good insulator.
What is an element that is not a good conductor and good isolator?
It is a semi conductor
Is sodium a semi conductor?
No, sodium is a metal and is not a semiconductor. Semiconductors are materials that have conductivity between that of a conductor and an insulator. Sodium is a good conductor of electricity due to its metallic properties.
What is extrinsic conductor?
Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. Two types of impurities are added to an extrinsic semi conductor. When impurities belonging to third group are called as trivalent or acceptor impurities such as boron, aluminum, indium or gallium when these impurities are added in pure semi conductors they form p-type semi conductor. And similarly when impurities belonging to group fifth called as penta valent or donor impurities such as arsenic, antimony, bismuth or phosphorus are added to a semi conductor they form N-type semi conductor .
Why carbon isn't a good semi conductor?
Beg your pardon but Carbon is a good semi conductor - it is used in most small resisters.
Is silicon a good conductor at energy?
semi conductor. a good semi conductor. It can also be n or p doped to increase it's conductivity
An element is a good conductor when it?
is a semi-metal
