This resource, part of the Spectroscopy Lab Suite, illustrates the physics of a semiconductor Diode Laser. Students can create conduction and valence band energy levels and build in a bias due to impurity doping. The...
This resource, part of the Spectroscopy Lab Suite, simulates optical transitions in a pumped infrared detector. In this simulated experiment, impurity states are initially populated with visible light. Infrared...
This resource discusses the meaning of quantum wavefunctions in terms of measurement probabilities. The double-slit experiment is used to motivate the concept of probabilistic measurements. A shockwave applet is then...
This resource discusses the energy levels of a periodic solid, and the effects of impurities on the energy levels. Applications of the energy levels to light emission and color are explored. The site includes an...
This resource illustrates the construction of scattering state wavefunctions in one dimension for a piece-wise constant potential. A barrier or well can be created from two potential steps, that can be of different...
