DIAMOND-HARD HEAT SINKS
General Electric researchers have synthesized isotopically pure diamonds composed almost entirely of carbon-12 atoms that conduct heat 50 percent better than their natural counterparts. High-thermal fluence heat sinks for microelectronics will be their first important application.
Everyone knows that no material beats diamonds for hardness. But it is less well known that nothing in nature conducts heat as well. Recently, man-made diamonds have been developed that can transmit heat and light even better than their natural counterparts.
