Materials
Further information: List of semiconductor materialsThere are many III-V and II-VI compound semiconductors with high bandgaps. The only high bandgap materials in group IV are diamond and silicon carbide (SiC).
Aluminum nitride (AlN) can be used to fabricate ultraviolet LEDs with wavelengths down to 200-250 nm.
Gallium nitride (GaN) is used to make blue LEDs and lasers.
Boron nitride (BN) is used in Cubic boron nitride.

Famous quotes containing the word materials:
“If our entertainment culture seems debased and unsatisfying, the hope is that our children will create something of greater worth. But it is as if we expect them to create out of nothing, like God, for the encouragement of creativity is in the popular mind, opposed to instruction. There is little sense that creativity must grow out of tradition, even when it is critical of that tradition, and children are scarcely being given the materials on which their creativity could work”
—C. John Sommerville (20th century)
“Artists, whatever their medium, make selections from the abounding materials of life, and organize these selections into works that are under the control of the artist.... In relation to the inclusiveness and literally endless intricacy of life, art is arbitrary, symbolic and abstracted. That is its value and the source of its own kind of order and coherence.”
—Jane Jacobs (b. 1916)
“In daily life what distinguishes the master is the using those materials he has, instead of looking about for what are more renowned, or what others have used well.”
—Ralph Waldo Emerson (1803–1882)
