Discover how researchers are revolutionizing lab-grown diamonds to pave the way for cutting-edge technology in computers, optics, and sensors. These diamonds are not meant for jewelry but rather for high-tech applications.
A recent study by scientists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and Princeton University delves into innovative methods for growing diamonds at lower temperatures than traditional techniques. Diamond’s unique properties make it an ideal material for semiconductors due to its ability to withstand high voltages and efficiently dissipate heat.
“Our work at PPPL aims to advance microelectronics by exploring materials and processes crucial for maintaining America’s competitive edge in this field,” explained Igor Kaganovich, Principal Research Physicist at PPPL.
Traditionally, lab-grown diamonds require high temperatures that exceed what computer chips can endure. Scientists are now striving to develop low-temperature growth methods without compromising diamond quality.
“Lower-temperature diamond growth could revolutionize silicon-based manufacturing and enhance the silicon microelectronics industry,” noted Yuri Barsukov, lead author of the study and computational research associate at PPPL.
Past experiments using plasma-enhanced chemical vapor deposition revealed that acetylene plays a role in diamond growth but also contributes to soot formation, which hinders performance in optics, sensors, and chips. Understanding how acetylene influences diamond or soot formation is key.
