Diamond is possible to dope to create semiconductors, and there is strong potential to utilize the nitrogen vacancy centers for memory storage and quantum computation.
With the best ability to transfer heat, diamond can replace many silicon and gallium nitride substrates for devices. This means fuel efficiency increases, extended battery ranges, faster charging, better signal strength of cellular towers, extended range for phased-array radar with military applications, or higher power with electronics.
And this is only the beginning…
