Researchers at ETH have studied in detail how single moving electrons can cause a material to become magnetic. Using quantum simulators, researchers in the U.S. have created images made of coloured ...

Single electrons in quantum dots can be disturbed by the apparatus used to measure them. The disturbance can be mediated by incoherent phonons — literally, noise. Engineering acoustic interference ...

(Nanowerk News) New types of solotronic structures, including the world's first quantum dots containing single cobalt ions, have been created and studied at the Faculty of Physics at the University of ...

Colloidal quantum dots (QDs) constitute a platform to explore various quantum effects. Their size-dependent colors are essentially a naked-eye, ambient-condition visualization of the quantum ...

Physicists in Germany have developed a new method for generating tunable wavelengths, as well as more easily switching back and forth between two wavelengths, employing quantum-dot lasers. The finding ...

Quantum dots and quantum wells represent pivotal semiconductor nanostructures whose quantum confinement effects yield discrete energy spectra and highly tunable optical and electronic properties.
