Hi All,(adsbygoogle = window.adsbygoogle || []).push({});

While going through quantum conductnace derivation, I got stuck by an integral.

I = ((e*(h/2pi))/(m*pi)) Integral from 0 to infinity

dt / ( exp (((((h/2pi)^2 * t)/(2*m)) - Ef) / kT)) + 1)

The answer is

I = (2e/h)*kT*ln(1 + exp(Ef/kT))

I am stuggling to find the answer. Any help will be appreciated.

Thanks
