Polyaniline (PANI) nanotubes configured as a field effect transistor (FET) exhibits a p–n junction diode behavior. The forward-bias current can be modulated by a gate voltage; turning on at negative gate voltage and turning off at positive gate voltage. An energy band diagram model has been...
process.This fixed charge region is known as depletion region or space charge region which is the region the free carriers have left.It is called as depletion region since it is depleted of free carriers.(b) Energy-band diagram for the p-n junction in thermal equilibriumn-typep-typeECECEF...
I am now having an issue understanding how to create the p-i-n junction energy band diagram profile. I have attached an .mph file with the geometry and the doping. I have the p side metal contact at -5 V and the n side metal contact at 0 V (reverse bias). However, ...
