Chemical analysis of a silicon crystal reveals gallium at a level of 3.091×10−8 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?
This is a question from the second midterm of 3.091x by edx. Stop cheating, it's silly and pointless.
antonio how did u end up here it is hypocrazy
Let's play around! Go GO Go!!! FIre in you hole!
