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, ...

Over the past two decades, a new area at the interface of semiconductor physics, electronics and quantum mechanics has been gaining popularity among theoretical physicists and experimenters. This new ...

- IBM Research is the first to synchronize electron spins and image the formation of a persistent spin helix. - Spintronics could enable a new class of magnetic-based semiconductor transistors ...

Researchers synthesized a fluorinated electron-acceptor for use in organic semiconductors. The high electronegativity of the fluorine substituents enhanced the electron-accepting properties of the ...

Conjugated polymers and small molecules, as typically used in organic light-emitting diodes (OLEDs) or solar cells, are undoped semiconductors. When these semiconductors are sandwiched between two ...
