Measuring the quantum state of photoelectrons
A photoelectron, emitted due to the absorption of light quanta as described by the photoelectric effect, is often characterized experimentally by a…
3R-WS2 crystals as a breakthrough in compact entangled photon sources
In a breakthrough that promises to revolutionize quantum photonic systems, researchers have successfully demonstrated a high-performance, ultracomp…
Ultrafast pump-probe phase-randomized tomography
Measuring fluctuations in matter’s low-energy excitations is the key to unveiling the nature of the non-equilibrium response of materials. A prom…
Fluorine-modified passivator for efficient vacuum-deposited pure-red perovskite light-emitting diodes
Vacuum-deposited perovskite light-emitting diodes (PeLEDs) have demonstrated significant potential for high-color-gamut active-matrix displays. Des…
A computational spectrometer for the visible, near, and mid-infrared enabled by a single-spinning film encoder
