Control over friction, from small to large scales

Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, even at large scales, ...

Guiding the design of silicon devices with improved efficiency

Silicon is one of the most pervasive functional materials of the modern age, underpinning semiconductor technologies ranging from microelectronics to solar cells. Indeed, silicon transistors enable computing applications ...

What do you do with a shrunken laser?

The laser is so small you need a microscope to see it properly. But it's not just the size that scientists at Sandia National Laboratories are excited about.
