Assume that the mean scattering in a semiconductor is only dependent on temperature and that dependence to be defined as T^(1.5)and effective electron mass to be independent of temperature. Electron mobility of a semiconductor at 80K is given to be 2,000cm²/m.s. Calculate the electron diffusion constant for this semiconductor at 120K.
