Question

1. It is common to dope silicon to change the band gap structure in ways that can be used to make transistors and other electronic components. For silicon to which 8.3 x 10²¹ atoms/m³ of antimony have been added: (a) what is the weight percent of antimony, and (b) what is the atom percent of antimony present. Bonus question: will antimony make silicon a p-type conductor, in which holes are the major charge carrier, or an n-type conductor in which electrons are the major charge carrier and why ?
