There was a an engineer several years ago developing a process to create large sheets of diamond. He claims to have received numerous death threats.

  Was he related to this? http://www.innovations-report.com/html/reports/life-sciences/a-155-carat-diamond-with-92-mm-diameter.html http://www.innovations-report.com/html/reports/life-sciences... https://en.wikipedia.org/wiki/File:Single-crystal_CVD_diamond_disc.jpg https://en.wikipedia.org/wiki/File:Single-crystal_CVD_diamon...

    Don’t think so. It was a guy in the USA, about 10 years ago. Though looks like many are doing it now with CVD. Diamond semiconductors are the holy grail, though there is current work growing diamond heat spreaders directly under GaN active regions.

      That was probably the Apollo Diamond guy: https://www.wired.com/2003/09/diamond/ https://www.wired.com/2003/09/diamond/ CVD is probably the better technology for producing bulk diamond, since it doesn't require the extreme temperatures and pressures of the HPHT process; and there's existing CVD processes and equipment from the semiconductor industry which provide a good body of knowledge to work with. CVD grows plates of diamond, whereas HPHT makes small cubes.

        Yes, that was it. Thanks.
