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, ...
In a study published in Nature Materials, scientists at Cavendish Laboratory have found two new approaches to enhancing organic semiconductors. Emptying of valence and deeper-valence bands through ...
