In this chapter you get to experience the operation of a PN junction. Scroll down to the first Scene.
Imagine we magically connect P-type and N-type pieces of Si together. The doping concentration of the p-side is 5E13 per cm^3. You can choose the doping concentration of the N side.
N Doping Density (per cm3):
You can reset the simulation by clicking on the reset button. Scroll down and fill out the survey once you are done.
In this scene you can see what happens when we apply a voltage across a PN junction. Here the formation of the depletion region is fast forwarded. You need to enter your participant ID again.
N Doping Concentration (per cm3):
Applied Voltage (V)
This last scene shows how minority carrier concentrations change with bias voltage and doping levels. Please scroll down, enter your ID, and follow the prompts.
Note that you if hover your mouse over the concentration curves you see the exact values.
