The topological insulator Bi2 Se3 has been studied by Laser ARPES at MIT, USA. These are the first band structure results using the ARTOF 10k spectrometer and both the bulk and surface bands are visible even though the sample was probed at room temperature and in non-optimal vacuum.

In ordinary insulators such as diamond the occupied and unoccupied electronic states are separated by a large energy gap. This gap prevents current flow when an electric field is applied. In topological insulators however, electrons can bypass the energy gap by moving in surface states. This new class of materials exhibit unusual properties which may be important for quantum computing.
