In a p-type semiconductor, the germanium is doped with elements that have an incomplete outer shell of electrons like aluminum, boron, and gallium.
The germanium cubic unit cell has 8 atoms per unit cell and an edge length of 5.65 Å. Calculate the mass of boron in mg if a 5 cm3 sample of the semiconductor is 2 ppm B.
