I can not find this in my book or online. I am working on electron diffusion current densities and I can not figure out if my book example is incorrect or if I am not understanding the formula.
So I know Jndiff = -qDn(-dn/dx)
I know how to find Dn using Einstein's relation using electron mobility and thermal voltage.
The q is the charge in C correct? Is it just a value of 1? If you find it using Einstein's relation I always get something like 1.01. Am I incorrect?
Is the last part the concentration gradient?
Do I have to convert anything because I know the answer is supposed to be in A/cm^2 and I get A/cm*um
If you help explain all this jiberish I would greatly greatly appreciate it.
