Are the following formulas the correct solution to this question? Thanks in advance for any help!(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Write down equations for the electron and hole concentrations n and p in a semiconductor, in terms of [tex]N{c}[/tex] or [tex]N{p}[/tex], the Fermi level position [tex]E{f}[/tex] and the temperature, T.

2. Relevant equations

3. The attempt at a solution

n= [tex]N{c}[/tex]exp[-([tex]E{c}[/tex]-[tex]E{f}[/tex]) / kT]

n=electron

[tex]N{c}[/tex]=Number of energy levels, conduction

[tex]E{c}[/tex]=Energy levels, conduction

[tex]E{f}[/tex]=Fermi energy levels

k=Boltzmann's constant

T=Temperature

p= [tex]N{v}[/tex]exp[-([tex]E{f}[/tex]-[tex]E{v}[/tex]) / kT]

p=holes

[tex]N{v}[/tex]=Number of energy levels, valence

[tex]E{v}[/tex]=Energy levels, valence

[tex]E{f}[/tex]=Fermi energy levels

k=Boltzmann's constant

T=Temperature
