In class Monday we established that the number density of free electrons in silicon was 1.09E+16 electrons per cubic meter. Now calculate the number of free electrons per silicon atom. The density of silicon is 2.33 Mg/m3 ; the atomic mass of silicon is 28.085 g/mole. Consider silicon which has a band gap of 1.11 eV and a measured conductivity of 0.00034 /ohmm at 300K. Its electron mobility is 0.145 m^2/(V x sec) and its hole mobility is 0.050 m^2/(V...
