This 10 x 10 mm wafer uses Group4 Labs' own technology to atomically attach a single gallium nitride layer to a 25-micron-thick synthetic diamond substrate. The exterior has an atomically smooth finish with a gallium-facing surface that is epi-ready for further epitaxial deposition. It comes freestanding or on a disposable silicon wafer mount. It uses the sub-nanometer proximity of the chip's active region to the diamond to extract heat from the chip's core almost the very instant it is generated, lowering heat build-up during high-power and high-speed transistor applications. The diamond's thermal conductivity is about 3-30 times more than ordinary semiconductors, boosting a transistor array's power-density by at least 10-100 times. It sells for $500-$600 per unit based on quantity. Group4 Labs LLChttp://rbi.ims.ca/4928-637
Major changes are happening in the world of 3D printing and additive manufacturing materials, machines, and software. If the industry -- and the design engineers and OEMs it serves -- are to grow, all three areas must become much more tightly integrated.
Americans spent more than $60B on their pets in 2015. Folks are definitely spending their money on more than dog food. We’re spending on things like dog spas and fancy toys, and as you can imagine, the wearables market is becoming well represented here.
Time was when sports equipment was made only from common, everyday, low-tech materials. But now sports equipment has a new, high-tech ingredient that is helping players take their game to the next level.
