Chemical analysis of a silicon crystal reveals gallium at a level of 3.091×10−4 atomic percent. Assuming that the concentration of thermally excited charge carriers from the Si matrix is negligible, what is the density of free charge carriers (free carriers/cm3) in this Si crystal?

Answer 1

Got the answer thanks anyway

Answer 2

How did you get the answer? or what is your answer?

Answer 3

what is value for silicon in gallium

Answer 4

Don't give an answer. Just explain step by step by inserting the data above into the formula. So we can understand how to answer.

Answer 5

This is a question from the second midterm of 3.091x by edx. Stop cheating, it's silly and pointless.
