energy band n (Physics / Atomic Physics) Physics a range of energies associated with the quantum states of electrons in a crystalline solid. In a semiconductor or an insulator there is a valence band containing many states, most of which are occupied. Above this is a forbidden band with only a few isolated states caused by impurities. Above this is a conduction band containing many states most of which are empty. In a metal there is a continuous valence-conduction band See also energy gap How to thank TFD for its existence?

We do not include the detailed nonparabolicity of the GaSb energy bands at [GAMMA]. At the Argonne meeting, Daresbury scientists noted the effect in gadolinium-150 and Argonne researchers reported a superdeformed energy band in dysprosium-151. GLAST is a next generation high-energy gamma-ray observatory designed for making observations of celestial gamma-ray sources in the energy band extending from 10 MeV to more than 100 GeV. |
