Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by ...

However, two recent papers show that an even better bet could be the absence of one electron (known as hole) or more precisely its spin 1,2.

A hole is essentially a missing electron in a semiconductor. Both holes and electrons possess spin, which can adopt one of two states: up or down, analogous to 0 and 1 in classical bits.

"The higher the spin, the more energy the black hole can release." Black holes may leak more energy to their surroundings than previously suspected — and the faster these voids spin, the more ...

Researchers at ETH Zurich have developed a new technique to better understand how electrons interact within materials. By ...

To understand spin, consider electrons orbiting the ... This pairing of one excited electron and one hole is called an exciton. Excitons are formed when the energy from light gets converted ...
