PN Junction & Diode

This interactive simulator explores PN Junction & Diode in Electricity & Magnetism. Band cartoon and Shockley-style I(V); ideality, temperature, I₀ scale. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Electricity & Magnetism.

Key terms

  • junction
  • diode
  • pn junction diode
  • electricity
  • magnetism

How it works

Forward bias shrinks the depletion region (cartoon width); reverse bias widens it and current saturates toward −I₀ in this ideal model.

Key equations

I = I₀ (e^{V/(nV_T)} − 1)
