Homework Statement
The Fermi level lies 0.516 ev below the conduction band in a sample of silicon at
300 degrees K.
Homework Equations
majority carrier concentration for n-type
n = 1/2[(Nd -Na) + sqrt((Nd-Na)^2 + 4(ni^2)]
minority carrier concentration for n-type
p= ni^2/Nd-Na
where Nd = density of donor atoms
Na = density of acceptor atoms
The Attempt at a Solution
My question is how do I calculate or find out what Na and Nd are?
