- An electron hole is a conceptual way of representing the absence of an electron from a full valence band in a solid-state material123. It is not a particle, but a quasiparticle with a positive charge1. Electron holes can interact with electrons to form excitons, which can condense into electron-hole droplets under certain conditions4. Electron holes are important for understanding the electrical and optical properties of semiconductors234.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.An electron hole (often simply called a hole) is the absence or lack of an electron where an electron would normally be in an atom. Because electrons are negative and their charges are balanced by the positive protons, electron holes are positive in charge. Electron holes are not particles, they are classified as quasiparticles.simple.wikipedia.org/wiki/Electron_holeIn solid-state physics, an electron hole (usually referred to simply as a hole) is the absence of an electron from a full valence band. A hole is essentially a way to conceptualize the interactions of the electrons within a nearly full valence band of a crystal lattice, which is missing a small fraction of its electrons.wiki.alquds.edu/?query=Electron_holeThe electron hole model is a simplistic way of modeling (looking at) the absence of an electron at atomic level. It can be used in the shell model for atoms and also in the band structure for crystalline materials and quasi-crystals, also in materials such as glasses.en.wikipedia.org/wiki/Talk:Electron_holeElectron-hole droplets are a condensed phase of excitons in semiconductors. The droplets are formed at low temperatures and high exciton densities, the latter of which can be created with intense optical excitation or electronic excitation in a p-n junction.en.wikipedia.org/wiki/Electron-hole_droplets

In physics, chemistry, and electronic engineering, an electron hole (often simply called a hole) is a quasiparticle denoting the lack of an electron at a position where one could exist in an atom or atomic lattice. Since in a normal atom or crystal lattice the negative charge of the electrons is balanced by the positive … See more

Non-radiative recombination is a process in phosphors and semiconductors, whereby charge carriers recombine releasing phonons instead of photons. Non-radiative recombination in optoelectronics and phosphors is an unwanted process, lowering the light generation efficiency and increasing heat losses.
