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
