electron hole

Furthermore it will also leave behind an electron hole that can flow as current exactly like a physical charged particle.

An alternate meaning for the term electron hole is used in computational chemistry.

The electron hole was introduced into calculations for the following situations:

There are two types of charge carrier in a semiconductor: free electrons and electron holes.

Examples include lines of force, centers of gravity, and electron holes in semiconductor theory.

Now we're thinking about the effective mass equation for the relative motion of electron hole pair when the external field is applied to a crystal.

(This is the equivalent to giving electron holes to the conductive layer.)

At the boundary between the emissive and the conductive layers, electrons find electron holes.

The current is caused by electron hole pairs being swept across the electric field of the depletion region when generated thermally near the edge.

In turn, this leaves behind a positively-charged electron hole (an abstraction for the location from which an electron was moved).

The heat source will cause charge carriers (electrons in an n-type, electron holes in a p-type) to move away from the lead.

It is a quasiparticle formed by quasiparticle-quasiparticle interactions, since both plasmons and electron holes are collective modes of different kinds.

This latter process may also be described as the injection of electron holes into the HOMO.

An exciton is a bound state of an electron and an electron hole which are attracted to each other by the electrostatic Coulomb force.

When light is absorbed by a material such as a semiconductor, the number of free electrons and electron holes increases and raises its electrical conductivity.

Electrons excited to the conduction band also leave behind electron holes, i.e. unoccupied states in the valence band.

Metal oxides show enhanced photocatalytic activity with the increase in surface defects in the crystals as this can alleviate electron hole separation.

The second is an effect known as "recombination", where the electrons created by the photoelectric effect meet the electron holes left behind by previous excitations.

An electron hole is the conceptual and mathematical opposite of an electron, useful in the study of physics, chemistry, and electronic engineering.

This creates electron holes, or unoccupied levels, in the valence band, and very loosely held electrons in the conduction band.

It is often used to determine the effective mass of charge carriers (electrons and electron holes), allowing investigators to distinguish among majority and minority carrier populations.

This applied voltage causes the upper P-N junction to 'turn-on' allowing a flow of electron hole from the emitter into the base.

An increase in photocatalytic activity was observed due to the creation of intermediate states that inhibits photogenerated electron hole recombination, allowing redox reactions.

Spectroscopic studies, however, show that the two Ru centers are equivalent, which indicates the ease with which the electron hole communicates between the two metals.

In condensed matter systems, specifically in some semiconductors, there are states called excitons which are bound states of an electron and an electron hole.
