Researchers have come up with a way to turn silicon into a direct bandgap semiconductor, opening the door to the manufacture of ultrathin silicon solar cells.

The physics of light absorption in silicon is such that while a photon changes the electron's energy state, a phonon is simultaneously needed to change the electron's momentum state. "Since the ...

In this work, researchers investigated a detection scheme facilitated by a photon-phonon coupled by a Cooper pair in a ...

Chinese scientists say they have "teleported" a photon particle from the ground to a satellite orbiting 1,400km (870 miles) away. For many, however, teleportation evokes something much more exotic.

However, in a material, this emission process can also be accompanied by the emission of a phonon — a quantized lattice vibration — and so the emitted photon will be lower in energy.

By absorbing energy in the form of a phonon (heat) or a photon (light), electrons can gain enough energy to jump to the conduction band. The band gap is the energy difference between the highest ...

By creating a new way for light and matter to interact, researchers at the University of California, Irvine have ...

“In indirect bandgap materials, like silicon, an additional component – a phonon – is needed to provide the electron the momentum necessary for the transition to occur. Since the likelihood of a ...
