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
