Molecules in collective ecstasy

"What we see here is energy transfer that is much faster than in any semiconductor," says Jakob Heier. The physicist works in Empa's Functional Polymers lab, and the discovery he has made with his team could cause a stir ...

Twisting 2-D materials uncover their superpowers

Two-dimensional (2-D) materials, which consist of a single layer of atoms, have attracted a lot of attention since the isolation of graphene in 2004. They have unique electrical, optical, and mechanical properties, like high ...

First ultra-low threshold continuous-wave lasing in GeSn

Transistors in computer chips work electrically, but data can be transmitted more quickly with light. Researchers have therefore been looking for a way to integrate a laser directly into silicon chips for a long time. A team ...

Electro-optical switch transmits data at record-low temperatures

A silicon optical switch newly developed at Sandia National Laboratories is the first to transmit up to 10 gigabits per second of data at temperatures just a few degrees above absolute zero. The device could enable data transmission ...
