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

Images of relativistic electrons trapped in graphene quantum dots have been taken by physicists in the US and Japan. The ability to confine and control electrons in such a way could play an important ...

Spin device: in this diagram of the spin valve the nanowire runs between a source and drain (both shown in gold) and the locations of the two quantum dots on the nanowire are denoted by the dashed ...
