This video shows an electronic structure calculation of bulk Si using Band Structure Lab. Several powerful features of this tool are demonstrated, including the following:

• band structure plots for many bands and central bands
• zooming in on the top of the valence bands
• effective mass table
• 3D representations of unit cell and larger lattice, with rotations and orthoscopic projection
• running a new calculation for increasing values of biaxial strain
• cycle through band structures for increasing strain values showing the distortions in bands due to strain
• plot band gap and band edges vs. strain

Researchers should cite this work as follows:
