Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged "hole," moving together in a semiconductor. Created when an electron ...

Excitons, quasiparticles formed by an electron and a hole, transfer energy without a net charge. Physicist Ivan Biaggio ...

Ultrawide-bandgap semiconductors—such as diamond—are promising for next-generation electronics due to a larger energy gap between the valence and conduction bands, allowing them to handle higher ...

Steady-state PL spectra were measured using low-intensity continuous wave (cw) excitation at 532 nm ... core/shell QDs exhibit an inverted geometry due to which both an electron and a hole exhibit a ...

“For example, we discovered that the excitation of these fluctuations is related to a particular motion of electrons, specifically the electron holes mentioned in the article. If we manage to fill ...

The researchers state that the discovery of this extremely high-energy neutrino is the first concrete proof that the universe produces neutrinos at these incredible energy levels.

Plasmons are the collective oscillations of the electron gas in a metal or semiconductor ... allowing plasmon excitation by standard optical sources and methods. The field of plasmonics is ...

They are in essence the eigenmodes of a material system that correspond to oscillations, at optical frequencies, of the electron liquid ... excited externally. This excitation field may be optical ...

The entorhinal cortex (EC) plays a pivotal role in memory function and spatial navigation, connecting the hippocampus with the neocortex. The EC integrates a wide range of cortical and subcortical ...

We present a fully quantum model for the excitation of a bound electron based on the “free-electron bound-electron resonant interaction” (FEBERI) scheme. The bound electron is modeled as a quantum two ...

However, there’s a catch. Before electrons can be accelerated by these shock waves, they need to contain a certain amount of energy to begin with. Nobody knows how electrons gain this initial energy.
