Question 64
ECNAT2 marksNeeds review
Consider that the concentration of electrons in a semiconductor bar varies linearly from
at
to
at
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
, thermal voltage is
and electron charge is
Coulomb.] The density of electron diffusion current (in A/mm
) is ___. (rounded off to two decimal places)Log in to check the answer
