When a large number of atoms are brought together to form a crystal, the interaction between the atoms causes the discrete energy levels to spread out into energy bands.
However, when a large number of atoms are brought together to form a crystal, the interaction between the atoms causes the discrete energy levels to spread out into energy bands.
In LEDs, as in other semiconductor devices such as transistors, the "terminals" are actually two semiconductor materials of different composition and electronic properties brought together to form a junction.
In a terrible moment called the Discontinuity, space-time has somehow been torn apart and reassembled, so that chunks of the earth's surface from many historical eras have been brought together to form a new patchwork planet.
Where Maraniss's essential biography of Bill Clinton, "First in His Class," was painted in great swaths of color, this is more a work of pointillism, myriad small dots of reportage brought together to form a vivid portrait.
These items were brought together to form the center of his exhibition, a collection of concrete ring sculptures that were cast in a swimming pool, using the chemicals and water that traditionally fill it.
Although their sources range from highly reputable (William Manchester's "Death of a President," Sally Bedell Smith's "Grace and Power") to iffy and presumptuous (authors like Donald Spoto, J. Randy Taraborrelli and Edward Klein), and include many online videos and museum sites, they are all brought together to form a powerful historical précis.
When the atoms are brought together to form a solid, these discrete energy levels become perturbed through quantum mechanical effects, and the many electrons in the collection of individual atoms occupy a band of levels in the solid called the valence band.
As a scenario construction principle, consistency is a heuristic that forces the scenario builder to reflect how 'bits and pieces' are brought together to form scenarios [4].
