What Happened To GaN And SiC?
By Mark LaPedus - 03 Feb, 2015 - Comments: 6

About five years ago, some chipmakers claimed that traditional silicon-based power MOSFETs had hit the wall, prompting the need for a new power transistor technology. At the time, some thought that two wide-bandgap technologies—gallium nitride (GaN) on silicon and silicon carbide (SiC) MOSFETs—would displace the ubiquitous power MOSFET. In addition, GaN and SiC were supposed to pose a t... » read more

Avogy: Vertical GaN Power Devices
By Mark LaPedus - 02 Feb, 2015 - Comments: 0

Gallium nitride (GaN), a binary III-V bandgap material, has been used to make LEDs for the last several years. GaN has also been touted as the next big thing in power electronics and RF. To some degree, GaN has made inroads in RF, especially in high-end defense and aerospace applications. But the technology is having mixed success in power electronics. Today’s GaN-on-silicon devices are l... » read more

Searching For The Next Power Transistor
By Mark LaPedus - 22 Jan, 2015 - Comments: 0

For decades, the industry has relied on various power semiconductors to control and convert electrical power in an efficient manner. Power semis are ubiquitous, as they are found in adapters, appliances, cars, elevators, switching power supplies, power grids and other systems. But today’s silicon-based power semiconductor transistor technologies, such as IGBTs, MOSFETs and thyristors, are ... » read more

A new study reveals that a majority of Americans are making some costly miscalculations regarding the performance of their existing PCs. The survey reveals that Americans lack financial savvy when faced with slow computers. Germany’s Merck KGaA, a pharmaceutical, chemical and life science company, announced an agreement with AZ Electronic Materials, under which Merck KGaA would acquire AZ.... » read more

The GaN Plan
By Ann Mutschler - 08 Apr, 2010 - Comments: 0

By Ann Steffora Mutschler Given the need to control power in high-end market segments such as servers, notebooks, mobile handsets and wired communications equipment, the market for gallium nitride (GaN)-based chips is poised for explosive growth. Case in point: Server farms are using more and more electricity, and the cost of that power is getting to be a significant fraction of the operati... » read more
