MVIS moving! ON TO SOMETHING BIG WITH THE LATEST NEWS INTEGRATED ELECTRONICS: Door Opens for Blue Lasers Scientists at Rensselaer Polytechnic Institute have found a way to grow aluminum nitride crystals that are large enough to slice into semiconductor substrates. No one else has been able to do that successfully. These crystals can be used to fabricate blue and ultraviolet lasers and blue and green light emitting diodes (LEDs). Semiconductor light sources have always been very attractive because of their ruggedness and economy, says Leo Schowalter, professor and chair of physics at Rensselaer. But the color of LEDs has been pretty much limited to red. Green and blue LEDs are also needed if we are to create traffic signals, automobile lighting, flat-screen television sets, and other applications where long life and high efficiency is important. In addition, blue and ultraviolet semiconducting lasers would make it possible to squeeze as much as 30 times more material onto a compact disk than can be done with the infrared lasers that are currently used. As a substrate, aluminum nitride is also ideal for semiconductors in wireless communications and power industry applications. Because aluminum nitride endures extreme heat, it can be used for microelectronic devices on jet engines. But growing aluminum nitride crystals is very, very difficult, says Schowalter. "Glen Slack, one of our research professors, demonstrated that you can grow aluminum nitride crystals in a tungsten crucible at 2300¡C. But at that temperature, the aluminum attacks the grain boundaries in the tungsten and the crucible doesn't survive very long." Schowalter and Slack have now solved the problem and formed a company, Crystal I.S., to create the aluminum nitride crystals.
