A p-n junction is obtained at a depth of 310−3 cm by diffusion of antimony (Sb) into p-type germanium. What is the acceptor concentration in the bulk Ge, if diffusion was carried out for three hours at 790∘ C?

Given:

Constant Sb surface concentration is 81018 cm3
The diffusivity of Sb in Ge at 790∘ C is 4.810−11 cm2/sec
Write answer in units of cubic centimeters, in scientific notation up to two decimal points
