Fraction of Vacancy in lattice terms of Energy Solution

STEP 0: Pre-Calculation Summary

Formula Used

Fraction of Vacancy = exp(-Energy Required per Vacancy/([R]*Temperature))
f_vacancy = exp(-ΔE_vacancy/([R]*T))
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

[R] - Universal gas constant Value Taken As 8.31446261815324

Functions Used

exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Fraction of Vacancy - The Fraction of Vacancy is the ratio of vacant crystal lattice to total no. of crystal lattice.
Energy Required per Vacancy - (Measured in Joule) - The Energy Required per Vacancy is E is the energy required to create one vacancy in the crystal lattice.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.

STEP 1: Convert Input(s) to Base Unit

Energy Required per Vacancy: 550 Joule --> 550 Joule No Conversion Required
Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_vacancy = exp(-ΔE_vacancy/([R]*T)) --> exp(-550/([R]*85))

Evaluating ... ...

f_vacancy = 0.459216783334827

STEP 3: Convert Result to Output's Unit

0.459216783334827 --> No Conversion Required

FINAL ANSWER

0.459216783334827 ≈ 0.459217 <-- Fraction of Vacancy

What are defects in crystal?

The arrangement of the atoms in all materials contains imperfections which have profound effect on the behavior of the materials.
Lattice defects can be sorted into three
1. Point defects (vacancies, interstitial defects, substitution defects)
2. Line defect (screw dislocation, edge dislocation)
3. surface defects (material surface, grain boundaries)

Why defect are important?

There are a lot of properties that are controlled or affected by
defects, for example:
1. Electric and thermal conductivity in metals (strongly reduced by
point defects).
2. Electronic conductivity in semi-conductors (controlled by substitution
defects).
3. Diffusion (controlled by vacancies).
4. Ionic conductivity (controlled by vacancies).
5. Plastic deformation in crystalline materials (controlled by
dislocation).
6. Colors (affected by defects).
7. Mechanical strength (strongly depended on defects).
