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 ...

The work 'Hyperbolic phonon-polariton electroluminescence in 2D heterostructures', led by researchers at the US Advanced ...

In laptops and cell phones, standard strain silicon technology is used to stretch ... gives us tremendous new freedoms," Li said. The phonon vibrational properties are key for superconductivity ...

Electron irradiation: High-energy electrons are used to create vacancies in the diamond lattice, which can then be filled by diffusing silicon atoms. One of the most notable features of SiV centers is ...
