Consider that the concentration of electrons in a semiconductor bar varies linearly from 2 $\times$ 10 17 cm -3 at x = 1 $m$ to $1\times$ 10 16 cm -3 at x = 4 $m$ along the x-direction. Assume that the concentration of electrons is not varying along other directions (that is along y- and z-directions). [Given: the mobility of electron is 1400 cm 2 V -1 s -1, thermal voltage is 25 mV and electronic charge is $1.6\times$ 10 -19 Coulomb.] The density of electron diffusion current (in A/mm 2) is __. (rounded off to two decimal places)
