Silicon (4 valence electrons) can be doped with arsenic (5 valence electrons) to make an n-type semiconductor. Assuming 1 in every 15 million silicon atoms is replaced with arsenic, calculate the carrier concentration, n, of the semiconductor. [Density of silicon = 2.33 g/cm3. Molar mass of silicon = 28.1 g mol–1.]
