# 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:

n_{e}n_{h}=(k_{b}T)^{3}/2(πh^{2})^{3}(m_{e}m_{h})^{3/2}(e^{-Eg(kBT)})
**Where,**
n_{e}n_{h} = Number Densities(Electron, Hole)
k_{B} = Boltzmann Constant
T = Temperature
h = Planck Constant
m_{e} = Electron Effective Masses
m_{h} = Hole Effective Masses
E_{g} = Band Gap
