CVD Diamond

The Geophysical Laboratory has made important advances in the growth of diamond by chemical vapor deposition (CVD).  Methods have been developed to produce single-crystal diamond at low pressure having a broad range of properties.

The CVD Lab at the Carnegie Institution of Washington has made great advances in diamond growth. Our goal of producing large, colorless, ultrahard and ultratough diamonds allows for the realization of a variety of applications that include diamond anvils for high pressure research; infrared and X-ray windows for high-power lasers and synchrotron beamlines; semiconductors; wear resistant and abrasive mechanical components; heatspreaders; micro-electrical machines (MEMS); high power electronics
