Superlattice castellated FETs Researchers from the University of Bristol and Northrop Grumman Mission Systems discovered a latch-effect in gallium nitride (GaN) that could lead to improved radio frequency device performance, crucial for enabling 6G devices. “We have piloted a device technology, working with collaborators, called superlattice castellated field effect transistors (SLCFETs),... » read more

GaN Power Semiconductors – 2025 Predictions
By Infineon - 06 Feb, 2025 - Comments: 0

GaN power semiconductors are on a tremendous growth trajectory. GaN is on its way to reaching more tipping points in its adoption in more industries. Consumer chargers and adapters have been the forerunner, more applications are expected to tip this year, with many others to follow in time. Still, there are some headwinds for GaN to reach this adoption level. Why is that and how can we overcome... » read more

Electrifying Everything: Power Moves Toward ICs
By Gregory Haley - 23 Jan, 2025 - Comments: 1

As electronic systems grow increasingly complex and energy-intensive, traditional power management methods — centered on centralized systems and external components — are proving inadequate. The next wave of innovation is to bring power control closer to the action — directly on the chip or into a heterogeneous package. This change is driven by a relentless pursuit of efficiency, scala... » read more
