A silicon semiconductor is dopedpq6y3 0vbmk5r- -orkqf/ +lwc n2vfejter4 ll:fqq6v+es *z n 1p:/v*with phosphorus. Will these atoms be donors or acceptors? vqfenv ej+*l:/e1 *fq6z r:pst 4n2lvWhat type of semiconductor will this be?
参考答案:
Phosphorus is in the same column of the periodic table as arsenic and each of these atoms have 5 electrons to share when placed in a lattice. Since the phosphorus would be replacing a silicon atom that has 4 electrons to share, there would now be an extra electron in the lattice, making this an n-type semiconductor in which the phosphorus atoms are donors.
