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 different energy states influence conduction.
See how electrons and holes respond to the effects of 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.
Observe how doping effect probability of electrons in band diagram.
Observe how Electron random walk changed when applied eletric field.
Observe how an electric field bends the banddiagram and follow electrons and holes on the banddiagram as they get accelerated and scattered.
