Abstract:

The movie illustrates the evolution of the constant energy contours of the band structure of undoped Bi2Se3 from binding energy Eb=0.7eV to Fermi-energy (EF). In this energy region, the band staructure evolve from the bulk valence band (BVB) to surface state band (SSB) (through the Dirac point), then to the region where the SSB and bulk conduction band (BCB) coexist.

perhaps death is the entrance to a time-symmetrical universe in which a person is born old and dies a baby. i know it sounds like sci-fi and bizarre concepts but if you truly think about the origin of the universe this could theoretically happen.

thats just what ive always suspected..............
