Any Pentavalent or Trivalent atom can be added to Silicon to create an "N" type or "P" type Material respectively. Which is used to create a PN Junction. Examples of Pentavalent atoms would be arsenic, antimony, and phosphorus, these Pentavalent atoms would be used to create an "N" Type material. Examples of Trivalent atoms are aluminum, boron, and gallium. Trivalent atom would be used to create "P" type material. I don't know why you would dope germanium, unless your talking about very old technology. Germanium use has slowed to a crawl since the discovery of intrinsic (pure) silicon.

How does doping change the properties of silicon and germanium?
Doping silicon and germanium involves introducing impurities into the crystal lattice to alter their electrical conductivity. Adding donor impurities, such as phosphorus, increases the number of free electrons, making the material n-type. Adding acceptor impurities, such as boron, creates "holes", increasing the material's conductivity and making it p-type. Overall, doping changes the electrical properties of silicon and germanium, allowing them to be used in electronics.
Which elements are used to make computer chips due to their ability to conduct electricity only under certain conditions?
Semiconductors, such as silicon and germanium, are used to make computer chips because they have the ability to conduct electricity under certain conditions. By selectively doping these materials with impurities, the behavior of electrons can be controlled to create the desired electronic components in the chip.
Why doping group iv elements?
Doping group IV elements like silicon and germanium is done in semiconductor manufacturing to alter their electrical properties. By introducing specific impurities into these materials, their conductivity can be enhanced or controlled to create p-type or n-type semiconductors, which are essential for building various electronic devices like transistors and diodes. This process allows for the precise engineering of the electrical behavior of semiconductor materials, enabling the development of modern technology.
What is silicon conductivity?
Silicon is a semiconductor material that has moderate conductivity. Its conductivity can be increased by adding specific impurities through a process called doping. This makes silicon a key material for building electronic devices such as transistors and integrated circuits.
What is the process of adding impurities to a semi conductor?
The process of adding impurities to a semiconductor is called doping. It involves intentionally introducing specific atoms of different elements into the semiconductor crystal lattice to alter its electrical properties. This process can either create an excess of electrons (n-type doping) or holes (p-type doping) in the semiconductor material.

Which serve as a donor impurity in silicon?
Common donor impurities in silicon include phosphorus and arsenic. These impurities have one more valence electron than silicon, making them donate an extra electron to the silicon crystal lattice, resulting in n-type doping.

What three elements that are used in semiconductors?
Silicon is the most common element used in semiconductors due to its abundance and well-understood properties. Germanium is another element used in semiconductors, although less commonly than silicon. Arsenic and phosphorus are often incorporated as dopants to introduce either additional electrons (n-type doping) or electron vacancies (p-type doping) in semiconductors.
How do you construct an n type semiconductor?
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.
How can we achive conduction in pure silicon?
Conduction in pure silicon can be achieved by introducing impurities into the crystal lattice through a process called doping. Silicon can be doped with elements like boron or phosphorus to create p-type or n-type semiconductors, respectively. These dopants add extra charge carriers to the silicon, allowing it to conduct electricity efficiently.
Why for making an n-type semiconductor silicon or germanium is doped with only fifteenth group element like phosphorus?
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
How do you make semi-metals?
Semi-metals, also known as metalloids, are typically made through a process called doping. This involves adding small amounts of impurities to a pure semiconductor material, such as silicon or germanium. The impurities alter the electronic properties of the material, making it exhibit characteristics of both metals and non-metals.

Silicon is a semiconductor material that has moderate conductivity. Its conductivity can be increased by adding specific impurities through a process called doping. This makes silicon a key material for building electronic devices such as transistors and integrated circuits.
