De generative semiconductor

In summary, a degenerative semiconductor is a material that has been intentionally doped with impurities to increase its electrical conductivity. This process, known as degenerative doping, can be used to create electronic devices and allows for better control of the flow of electricity. The most commonly used impurities in degenerative doping are elements from the third and fifth columns of the periodic table. Degenerative doping differs from non-degenerative doping in that it intentionally alters the conductivity of the semiconductor, while non-degenerative doping is used for other material properties. Degenerative semiconductors have a wide range of applications in electronic devices and components, including transistors, diodes, and solar cells.

ordinary Semiconductor: The Fermi level (Ef) is located within the gap, and its electronic density is around 10^18.

Degenerative one: Ef is located above the conduction band, and its electronic density is around 10^22. it conducts like a metal which has a low resistivity.

The correct term is:

"degenerate statistics"
 

1. What is a degenerative semiconductor?

A degenerative semiconductor is a type of material that has been intentionally doped with impurities to increase its electrical conductivity. This process can be used to create electronic devices such as transistors and diodes.

2. How does degenerative doping affect the properties of a semiconductor?

Degenerative doping increases the number of free electrons or holes in the semiconductor, making it more conductive. This allows for better control of the flow of electricity within electronic devices.

3. What are the most commonly used impurities in degenerative semiconductor doping?

The most commonly used impurities in degenerative semiconductor doping are elements from the third and fifth columns of the periodic table, such as boron, phosphorus, and arsenic. These impurities have one less or one more valence electron than the atoms in the semiconductor, creating free electrons or holes when added to the material.

4. How is degenerative semiconductor doping different from non-degenerative doping?

Degenerative doping involves adding impurities in a controlled manner to intentionally alter the conductivity of a semiconductor, while non-degenerative doping is used to modify other properties of the material, such as its optical or mechanical properties. Non-degenerative doping is also used in smaller amounts and does not drastically change the electrical conductivity of the semiconductor.

5. What are the applications of degenerative semiconductors?

Degenerative semiconductors are used in a wide range of electronic devices, including transistors, diodes, and integrated circuits. They are also used in solar cells, sensors, and other electronic components. The ability to control the conductivity of a semiconductor through degenerative doping allows for the creation of more complex and efficient electronic devices.
