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, ...
Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future ...
An ultra-short flash of light breaks the bond between the electron (red) and the hole (blue), enabling research on charge-transfer processes in atomically thin semiconductors. Credit: Lukas Kroll, Jan ...
