Black silicon is a semiconductor material, a surface modification of silicon with very low reflectivity and correspondingly high absorption of visible (and infrared) light. The modification was discovered in the 1980s as an unwanted side effect of reactive ion etching (RIE). Another method for forming a similar structure was developed in Eric Mazur's laboratory at Harvard University (1998).

Famous quotes containing the word black:
“Chastity prays for me, piety sings,
Innocence sweetens my last black breath,
Modesty hides my thighs in her wings,
And all the deadly virtues plague my death!”
—Dylan Thomas (1914–1953)
