In summary, there is a discrepancy in the values of the intrinsic concentration of silicon (ni) in different books, with some citing it as 1.1x10^10 cm-3 and others as 1.5x10^10 cm-3. However, a recent paper by A. B. Sproul, M. A. Green, and J. Zhao (1990) suggests that the commonly cited value of 1.45x10^10 cm-3 is not consistent with the best experimental and theoretical results. The paper proposes a new value of 1.08x10^10 cm-3, and reports an experimental measurement of 1.01x10^10 cm-3 with a

in some books, Si instrinct concentration(ni)=1,1x10^10cm-3, some books instrinct concentration(ni)=1,5x10^10cm-3. Why these values are different?

Maybe, this paper might be of help:
A. B. Sproul, M. A. Green, and J. Zhao, Improved value for the silicon intrinsic carrier concentration at 300 K , Appl. Phys. Lett. 57, 255 (1990)

Abstract

A recent review suggests that the commonly cited value of 1.45×1010 cm−3 for the silicon intrinsic carrier concentration at 300 K is inconsistent with the best experimental and theoretical results. An alternative value of 1.08×1010 cm−3 was suggested. A new experimental measurement of 1.01×1010 cm−3 is reported with an estimated one standard deviation uncertainty of only 3%. This appears to be the most accurate experimental determination of this parameter at any temperature.
 

FAQ: Intrinsic Concentrations are different in some books. Why?

Why are intrinsic concentrations different in some books?

There are a few reasons why intrinsic concentrations may vary in different books. One reason is that the value of intrinsic concentration can depend on the temperature and other environmental factors. Additionally, different books may use different methods or assumptions to calculate intrinsic concentration, leading to variations in the reported values.

Which book is correct about intrinsic concentrations?

There is no single "correct" value for intrinsic concentration. As mentioned, it can vary depending on the conditions and methods used. It is important to understand the context in which the intrinsic concentration is being used and to use the appropriate value for that specific situation.

How do intrinsic concentrations affect semiconductor properties?

Intrinsic concentrations play a crucial role in determining the electrical and optical properties of semiconductors. They influence the carrier concentration, conductivity, and bandgap energy of the material. Understanding the intrinsic concentration is essential for designing and optimizing semiconductor devices.

Why is the intrinsic concentration of a material important?

The intrinsic concentration of a material is important because it provides information about the material's intrinsic properties, independent of any external factors. It is a fundamental parameter that can be used to understand and predict the behavior of semiconductors and other materials.

Can the intrinsic concentration of a material change?

Yes, the intrinsic concentration of a material can change depending on the temperature, pressure, and other environmental factors. It can also be influenced by doping or other external modifications to the material. However, the intrinsic concentration remains a fundamental property of the material and is an important factor in its behavior.
