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...

recombination are processes by which mobile charge carriers (electrons and electron holes) are created and eliminated. Carrier generation and recombination...

there were a black hole with the same mass, charge and angular momentum as an electron, it would share other properties of the electron. Most notably, Brandon...

created. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors,...

An electron and an electron hole that are attracted to each other by the Coulomb force can form a bound state called an exciton. It is an electrically...

quantity for holes, called hole mobility. The term carrier mobility refers in general to both electron and hole mobility. Electron and hole mobility are...

smallest holes observable by humans include pinholes and perforations, but the smallest phenomenon described as a hole is an electron hole, which is...

Electron-hole droplets are a condensed phase of excitons in semiconductors. The droplets are formed at low temperatures and high exciton densities, the...

of a free electron and a hole, the stronger the optical absorption will be. The Airy tails slightly overlap even if the electron and hole are at slightly...

semiconductor: free electrons (mobile electrons) and electron holes (mobile holes which are missing electrons from the normally-occupied electron states). A normally-bound...

normal electron-electron or hole-hole scattering at the interface. Since the pair consists of an up and down spin electron, a second electron (hole) of opposite...

QDs. Nanoscale semiconductor materials tightly confine either electrons or electron holes. The confinement is similar to a three-dimensional particle in...

occurs in semiconductors. An electron and electron hole (electron-hole pair) can recombine giving up their energy to an electron in the conduction band, increasing...

shell while creating an electron hole where the electron was. An electron from an outer, higher-energy shell then fills the hole, and the difference in...

factors. For electrons or electron holes in a solid, the effective mass is usually stated as a factor multiplying the rest mass of an electron, me (9.11...

bond allows the bonded electrons of neighboring atoms to move into the "hole", leaving another hole behind, thus propagating holes throughout the lattice...

(negative) side contains freely-moving electrons, while the "p" (positive) side contains freely-moving electron holes. Connecting the two materials causes...

junction that converts photons into charge. The absorbed photons make electron–hole pairs in the depletion region. Photodiodes and photo transistors are...

required to promote an electron from the valence band to the conduction band. The resulting conduction-band electron (and the electron hole in the valence band)...

The absorption of light, generating excitons (bound electron-hole pairs), unbound electron-hole pairs (via excitons), or plasmons. The separation of...

In another example, the aggregate motion of electrons in the valence band of a semiconductor or a hole band in a metal behave as though the material...

carriers. For example, in semiconductors, an electron (or hole) with enough kinetic energy can knock a bound electron out of its bound state (in the valence...

(HCI) is a phenomenon in solid-state electronic devices where an electron or a “hole” gains sufficient kinetic energy to overcome a potential barrier...

the electron–hole pairs are generated in the high field region. The generated electron immediately moves into the N region, while the generated holes drift...

the radiation. Ionizing radiation produces free electrons and electron holes. The number of electron-hole pairs is proportional to the energy of the radiation...

electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons....

is the ratio of the hole impact ionization rate to that of electrons. For an electron multiplication device it is given by the hole impact ionization rate...

is a solid that upon irradiation with UV- or visible light generates electron–hole pairs that generate free radicals. Photocatalysts belong to three main...
