Element Six (E6), part of the De Beers Group, is a world leader in the development and production of synthetic diamond solutions.

Since 1959, E6's focus has been on engineering diamond materials to unlock innovative applications, including thermal management, optics, quantum and sensing.

Chemical vapour deposition (CVD) diamond is used as a thermal heat spreader to manage the huge power densities (>4 kW/cm2) associated with modern semiconductor devices, underpinning the exponential demand in internet bandwidth. Thanks to a thermal conductivity up to x10 higher than other solutions, diamond acts as the perfect platform to mount devices on. For example, gallium nitride power amplifiers mounted on diamond can be optimised to drop junction temperatures by >30%.

Our patented technology places us at the forefront of synthetic diamond innovation, enabling us to deliver competitive advantage to our customers through diamond-enabled solutions.
