What Do the Terms in the Semiconductor Density Equation Represent?

Click For Summary
SUMMARY

The discussion centers on the semiconductor density equation, specifically the terms Nc,v = 2 ((2πmc,vKT)/(h^2)). The variables K, T, and h are identified as Boltzmann's constant, temperature, and Planck's constant, respectively. The terms "c,v" refer to conduction and valence bands, while N represents the density of states, and m denotes the mass of the charge carriers. The clarification of these terms is essential for understanding semiconductor physics.

Homework Statement



Having some trouble with the following equation, I'm not sure what each term represents.

The problem I have is does c,v have something to do with conduction and valence? But what is N and m? And what does it mean when terms are separated by a comma?

Homework Equations



Nc,v = 2 ((2\pimc,vKT)/(h^2))


The Attempt at a Solution



From what I gather;

K=Boltmann's constant
T=Temperature
h=Planck's constant
Nc,v=?
mc,v=?

Please use latex, since I am guessing the "c,v" are subscripts. In that case you are right about conduction and valence. N is the number of energy levels in either the conduction or valence band (basically density of states) and m is the mass of the carrier.
 
Sorry, i'll make sure I use latex in future.

That's cleared things up for me. Thank you.
