When the number of electrons matches host lattice sites in a material, strong interactions between electrons can cause them to arrange themselves into an orderly pattern, forming what is known as an ...

Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by excited particles, due to photons of the same frequency triggering further ...

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 ...

In a study published in Nature Materials, a research team from the National University of Singapore (NUS) achieved a significant breakthrough by generating and directly observing electron-hole ...

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, ...

Physicists found why holes move slower than electrons in silicon: not defects, but higher intrinsic mass, supporting CMOS-based quantum, cryogenic, and space devices. The finding shows the difference ...

A team developed a novel method to successfully visualise electron-hole crystals in an exotic quantum material. Their breakthrough could pave the way for new advancements in computing technologies, ...
