Abstract The NP Junction: Long-Base Depletion Approximation tool is used to approximately calculate, and then graph, the distribution in an n- and p-type junction of :
  • Charge Density
  • Electric Field Intensity
  • Electrostatic Potential
  • Excess Carrier Concentration
  • Current Density
  • Current Density Amplitude
  • Depletion Width
  • Max Excess Hole Concentration
  • Max Excess Electrons Concentration
  • Junction Capacitance
  • 1 / C^2
