Two-layered molybdenum disulfide is one such van der Waals material, in which electrons can be excited using a suitable experimental setup. These negatively charged particles then leave their position ...

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 ...

Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future ...

Researchers at RWTH Aachen University and Forschungszentrum Jülich have uncovered important characteristics of double quantum dots in bilayer graphene, an increasingly promising material for possible ...

Scientists directly observed tiny lattice deformations in quantum dots caused by electron-hole pairs, key for advancing solar cells and LEDs. (Nanowerk News) When light hits solar cells, so-called ...
