Ap-n step junction in si has 1018 cm-3 net acceptors on the p side and 1014 cm-3 net donors on the n side. assume t = 300k, ni = 1.5 x 1010cm-3, find (a) the built-in potential and (b) extent of depletion region on n and p side. (c) explain how the built-in potential is related to the fermi level and what happens to vbi as a function of temperature in the range 30k to 500k.

Transfer of electrons. hope it !

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Wouldnt it be millileter
