The electronic and optical devices that we use on a daily basis, such as mobile phones, LEDs and solar cells use transistors and other parts that are consistently getting smaller and more compact.

Engineers at MIT have turned one of computing’s biggest headaches, waste heat, into the main act. By sculpting “dust-sized” silicon structures that steer heat as precisely as electrical current, they ...

Silicon solar cells were supposed to be running out of headroom, yet a new device has pushed their performance to 27.81% efficiency and reset expectations for what a single-junction cell can do. That ...

Circuit scaling is starting to hit a wall as the laws of physics clash with exponential increases in the volume of data, forcing chipmakers to take a much closer look at silicon photonics as a way of ...
