Mechanism 'splits' electron spins in magnetic material

Holding the right material at the right angle, Cornell researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet—a technique that could eventually lead to the development of more ...

Graphene key for novel hardware security

As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components ...

Ultrathin transistors for faster computer chips

For decades, the transistors on our microchips have become smaller, faster and cheaper. Approximately every two years the number of transistors on commercial chips has doubled—this phenomenon became known as "Moore's Law." ...
