A major challenge in modern surface science is to create ordered arrays of covalently linked organic nanostructures. By doping molecular electronic bands into highly conductive states, these ...

Semiconductor materials play an important part in developing nanophotonic technologies. Semiconductors are used for generating controllable photons as well as for confining and exploiting them for ...

Researchers at Lund University, Sweden, have grown single continuous GaAs nanowires consisting of segments of pure wurtzite and zincblende phases. Using photoluminescence spectroscopy, they found that ...

A ‘hole’ arises due to a missing electron in the valence band, which normally participates in covalent bonding between atoms. The absence of an electron creates a local absence of a negative charge, ...

Many modern electronic devices we use daily owe their existence to the process of semiconductor doping. Doped semiconductors are the result of careful modifications ...
