Define and describe the importance of depletion region and barrier potential.

Define Drift and Diffusion current in Semiconductor

The diode shown in Figure T9.2 is ideal. Determine the state of the diode and the values of vx and ix.

1) Write down V Anode - Anode equation for P-N diode with long enough neutral region and schematically draw V Anode - Anode curve. 2) How current level changes with doping concentration of p region? Schematically draw an VAnode - Anode curve of P-N diode with three different p-doping concentration (low, middle, high). 3) How current level changes with temperature? Schematically draw an VAnode IAnode curve of P-N diode with three different temperature (lower than room temperature, room temperature, higher than room temperature). -
