X-ray flashes reveal how electron-hole pairs tug at atoms inside quantum dots

When light hits solar cells, so-called electron-hole pairs are created: the electrons are excited and can move almost freely in the material—i.e. to generate electricity. The electrons will leave 'positive gaps," so-called ...

The first experimental realization of quantum optical skyrmions in a semiconductor QED system

Skyrmions are localized, particle-like excitations in materials that retain their structure due to topological constraints (i.e., restrictions arising from properties that remain unchanged under smooth deformations). These ...

First quantum confinement achieved without physical downsizing

Quantum confinement is a physical effect that occurs when the size of a material—usually a semiconductor or conductor—is reduced to the nanoscale, thereby restricting the movement of electrons or holes.
