IQE Greensboro expansion tied to company consolidation of operations and EV uses. And Toyota's new battery plant might have been a factor, too.

But as tools and processes advance, there's still room for breakthrough technologies.

The next generation of 2D semiconductor materials doesn't like what it sees when it looks in the mirror. Current synthesizing approaches to make single-layer nanosheets of semiconducting material for atomically thin electronics develop a peculiar "mirror twin" defect when the material is deposited on single-crystal substrates like sapphire. The synthesized nanosheet contains grain boundaries that act as a mirror,…

The eutectic structure of metals and ceramics occurs when multiple solid phases solidify from a liquid phase, forming a three-dimensional (3D) pattern through a self-organizing phenomenon. Traditionally, it was believed that eutectic structures could only be obtained through a melt-solidification process.

Renewable energy was big again this week after another quarter-billion-dollar round. Two media-related companies also made it into the top five — a rarity — in what was a slightly down week.
