Diamond still at the edge

摘要

For UK's Ascot-based, Element Six, a defining moment was the paper published in Science 297 p. 1670 (6 Sept. 2002) on the development of technology for producing free-standing, single crystal CVD diamonds (SSC-CVD diamond) with new material properties that 'far exceeded even the most optimistic expectations.' This semiconductor material should enable new electron devices. Three year later, E6 and JV partners have seen the emergence of two such devices: MESFET transistors and Schottky-barrier diodes.
