The interactive visualizations presented here provide an experiential learning experience for students taking introductory courses on semiconductor physics and devices. For best experience, use Google Chrome. In your browser, you may need to choose “view” and select actual size. Refresh your page if you feel your visualizations have become too slow.
The classical and quantum mechanical models of a Hydrogen atom, 1S, 2S, 2Px, 2Py, and 2Pz Orbitals
The potential and kinetic energies of an electron in a Hydrogen atom in classical and quantum mechanical models.
Bonding between two Hydrogen atoms and the formation of a Hydrogen molecule.
Hybridization of S and P orbitals in a Si Crystal, Valence and Conduction bands.
The relationship between kinetic energy and momentum in classical physics and for an electron in a crystal.
Electrons and Holes in various energy states and how they contribute to conduction.
See how electrons and holes respond to an electric field.
See how electron and hole populations change with time and temperature.
Doping is the process of adding impurities to an intrinsic semiconductor. See how it affects electron and hole densities.
Observe ensity of states and Fermi function in a semiconductor and how doping affects state occupancy and carrier statistics.
Observe how the random walk of electrons and holes are affected by an applied electric field.
Observe how an electric field bends the banddiagram and follow electrons and holes on the banddiagram as they get accelerated and scattered.
In addition to drift, we can have a net movement of electrons or holes when their concentrations are not constant in various regions of a semiconductor.
