current density across a scottky barrier

current density across a scottky barrier

(OP)
hi guys im currently in the middle of a project but i am stuck on one are. I am trying to find the derivation of the current density across a schottky barrier taking into account the lowering of the barrier due to the potential.

Please if any one can help i would be so grateful i would need the equations requied to complete this as well. Thank you for anyoen that can help in advance.

RE: current density across a scottky barrier

Perhaps I’m missing something, but surely the current density is simply the current divided by the cross-sectional area when measured along an equipotential surface. This is a function of the physical makeup of the structure rather than an equation. If the diode could be modelled as a tubular conductor, for example, the current density would be pretty uniform throughout, depending on the ohmic contacts at the ends "spreading" the current evenly into the rod.

Is it just me, or does this sound exactly like a HW problem some of us had many years back?

That was my impression too, but just enough doubt that I didn't red flag it.  I might have if logbook hadn't already answered it before I saw it.
