BZones - a JAVA applet to visualize Brillouin zones
Brillouin zones are an important concept in solid state physics. They are in reciprocal space of crystalline materials the geometrical equivalent of Wigner-Seitz cells in real space. Not every energy level of the electrons is allowed in a crystal.In k-space they form a band-structure, and duo to symmetry constraints this structure is periodic with the Brillouin zone. So if you want to read your band-structure calculation, you need a representation of the corresponding Brillouin zone with all the high symmetry points.
This Java applet displays the Brillouin zone of the crystal. Please choose your bravais lattice from the drop-down
list and enter the dimensions. Notice that due do the symmetry of your choosen crystall not all options are available.
