Phys.org / Atomic-level simulations predict transistor scaling limits

As the global semiconductor industry enters the so-called 2-nanometer process era, the actual size of transistors—the core components of semiconductor chips—still remains above 10 nm. How much smaller, then, can transistors ...

Phys.org / Deep Earth model traces 270 million years of seamount formation across oceans

Over 40,000 seamounts—undersea mountains that don't breach the ocean's surface—are scattered across the ocean floor. Some form linear chains, while others occur as dispersed, isolated features that are not part of well-defined ...
