Number Density of Electrons Calculator

In semiconductors, the number density of electrons is much less than in conductors and is artificially created by doping. Without doping, semiconductors have a number density between conductors and insulators. Calculate the density number of electrons in semiconductor material based on band theory.

Formula:

nenh=(kbT)3/2(πh2)3(memh)3/2(e-Eg(kBT)) Where, nenh = Number Densities(Electron, Hole) kB = Boltzmann Constant T = Temperature h = Planck Constant me = Electron Effective Masses mh = Hole Effective Masses Eg = Band Gap
