Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics.

(a) Schematics of the experimental setup for electron and photon scattering. (b) An atomic model of the pattern formed by the twisted bilayer graphene (30°-tBLG) crystal structure. (c) A low-energy ...

Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a ...

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic communications to quantum sensors, the manipulation of photons underpins ...

LEMONT, Ill.--(BUSINESS WIRE)--A new set of electron beam measurements puts the upgraded Advanced Photon Source (APS) at the top of the list of the world’s synchrotron X-ray research facilities. The ...

In a typical organic solar cell, an electron-donating material is interfaced with an electron acceptor. When the donor absorbs a photon, one of its electrons may jump across the interface, creating a ...

After few femtoseconds, the double excited state decays by electron emission, generating a higher charge state. Compared to ...
