We are hoping to apply the knowhow we acquired with SiC to other prospective materials of power devices, such as gallium nitride(GaN) and diamond, and develop other new products that contribute to the achievement of higher productivity.
Although it has the same size as the 87W adapter that came with the 15-inch model, it is still larger than the charger that has been popular in the market these days and has been downsized with gallium nitride(GaN).
Gallium nitride(GaN) is enabling a new generation of power switching devices that offer higher efficiency and switching speed than the traditional silicon MOSFET, to satisfy the demands of today's high-performance electronics. Veeco MOCVD systems provide key advantages for GaN-on-Si production, including low particle counts and excellent yields.
Power transistors fabricated using gallium nitride(GaN) technology are higher performing than traditional silicon power devices and, in this power conversion application, these eGaN FETs provide an 80% reduction in the driving power, a 25% reduction in on resistance, and 5% less power dissipation all in a very small, 3.19 cubic inch package.
For the last 15 years or so, Arakawa's research group has been approaching gallium nitride quantum dot research from the perspective of both condensed-matter physics and crystal growth technology, and in 2016, succeeded in fabricating a single-photon source that operates at the highest temperature achieved to date(77 degrees Celsius, hot enough to hard-boil an egg)(figure 3).
The interview extensively covers various areas of interests in answering the question of wider adoption of GaN devices by the semiconductor industry including differentiations of GaN devices, lowering of costs, latest device innovations, high-frequency plus small-size device operations, heat management, how GaN's markets would surpass silicon's markets and the future development of gallium nitride technology.
