Symmetric graphene quantum dots for future qubits

Quantum dots in semiconductors such as silicon or gallium arsenide have long been considered hot candidates for hosting quantum bits in future quantum processors. Scientists at Forschungszentrum Jülich and RWTH Aachen University ...

Researchers develop high-efficiency afterglow material

A research group led by Dr. Yang Bin from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has developed cadmium (Cd)-based perovskite single crystals with long afterglow and high luminous ...

Quantum dots form ordered material

Quantum dots are clusters of some 1,000 atoms which act as one large "super-atom." It is possible to accurately design the electronic properties of these dots just by changing their size. However, to create functional devices, ...

Making dark semiconductors shine

Whether or not a solid can emit light, for instance as a light-emitting diode (LED), depends on the energy levels of the electrons in its crystalline lattice. An international team of researchers led by University of Oldenburg ...

Alignment of quantized levels in valleytronic materials

National University of Singapore researchers have predicted that Landau levels belonging to different valleys in a two-dimensional (2D) valleytronic material, monolayer tungsten diselenide (WSe2), can be aligned at a critical ...

Electronic self-passivation of single vacancy in black phosphorus

NUS scientists discovered that a two-dimensional (2D) semiconducting material, known as black phosphorus (BP), exhibits an electronic self-passivation phenomenon by re-arranging its vacancy defects. This may potentially enhance ...
