This video shows the simulation and analysis of a pyramid-shaped quantum dot using Quantum Dot Lab. Several powerful analytic features of this tool are demonstrated, including the following:

  • visualization of specific 3D wavefunctions corresponding to discrete energy levels within the quantum dot
  • rotating the 3D volume of the quantum dot with wavefunction
  • applying cut planes along the x and y axes and moving the cut planes along those axes.
  • customizing the color scale used in volume rendering
  • scanning through the energy levels of the states inside the dot
  • viewing the transition and absorption curves
  • returning to the input section to change the size of the quantum dot and running a new simulation
  • comparing the absorption curves for different dot sizes
  • interactively zooming in on regions of the absorption plots
