If the impurity concentration is increased how the depletion width effected?
depletion layer decreases
How the depletion width effected If the impurity concentration is incresed?
As impurity concentration increases in a semiconductor, the depletion width decreases. This is because a higher concentration of dopants leads to a greater number of charge carriers, which enhances the electric field within the depletion region. Consequently, the potential barrier is more effectively neutralized, resulting in a thinner depletion layer. This effect is critical in determining the electrical characteristics of semiconductor devices like diodes and transistors.
What is soluble impurity?
A soluble impurity refers to a substance that dissolves in a solvent, typically water, and alters the properties of the solution. These impurities can affect various factors, such as conductivity, boiling and freezing points, and overall solution behavior. Common examples include salts, sugars, and some organic compounds. Soluble impurities are often measured in terms of concentration and can impact processes in chemical reactions, environmental science, and manufacturing.
What is lack of purity called?
Impurity or contamination.
What is a tetravalent impurity?
A tetravalent impurity refers to an impurity that introduces four valence electrons into a material's crystal lattice. These impurities can significantly impact the electrical and optical properties of the material due to their ability to alter the number of charge carriers within the material. Examples include elements like silicon or germanium in a crystal lattice of another material.
If the impurity concentration is increased how the depletion width effected?
depletion layer decreases
How the breakdown voltage of particular diode can be controlled?
By Varying the impurity concentration
Does water have a definite boiling point?
no it is depend upon concentration of impurity.
What causes depletion region across P-N junction?
The presence of mobile and bound charges on either sides of the pn junction causes the depletion layer. A pn junction is formed when a semiconductor is dopped with a pentavalent impurity on one side and a tri-valent impurity on the other side.on one side electrons will be more in number and on the other side holes will be more in number.At the junction the electrons combine with holes and there will be no charge carriers(i.e. electrons and holes) in that region.That region which is free from charge carriers is called depletion region.
Is coffee an impurity?
if dissolved in water, it can be called an impurity.
What is meant by step graded junction?
A step graded junction is the pn junction in which impurity concentration does not change abruptly from donor to acceptor but varies smoothly
Give me a sentence using the word impurity?
The impurity of the solution can be removed using various ways. This is a sentence using impurity word.
What is the effect of adding impurity on viscosty of liquid?
Adding impurities to a liquid generally increases its viscosity. This is because impurities disrupt the flow of the liquid molecules, leading to more resistance and a thicker consistency. The extent of the increase in viscosity depends on the type and concentration of impurities added.
What is a sentence for impurity?
An impurity is, essentially, something that makes it not pure. An example sentence would be: The impurity in the crystal, made the value go down.
What is a volatile impurity?
A volatile impurity is an impurity that can evaporate easily. Pharmacies use organic volatile impurities to manufacture certain types of drugs.
Why trivalent impurity is used?
Trivalent impurity is used to create a free electron when bonded with a silicon crystal.
How conductvity of semiconductors changes with the presence of impurities?
If the impurity is of type "n" - an element (the impurity) that has 5 electrons in its outer shell - conduction will be mainly via electrons. If the impurity is of type "p" - the atoms of the impurity has 3 electrons in its outer shell - the conduction will be mainly via holes.
