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
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
