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?

    what is value for silicon in gallium

    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.

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