Non-radiative lifetime

Index Non-radiative lifetime

Non-radiative life time is the average time before an electron in the conduction band of a semiconductor recombines with a hole non-radiatively. [1]

Carrier generation and recombination

In the solid-state physics of semiconductors, carrier generation and recombination are processes by which mobile charge carriers (electrons and electron holes) are created and eliminated.

Electron

The electron is a subatomic particle, symbol or, whose electric charge is negative one elementary charge.

Electron hole

In physics, chemistry, and electronic engineering, an electron hole (often simply called a hole) is the lack of an electron at a position where one could exist in an atom or atomic lattice.

Non-radiative recombination

Non-radiative recombination is a process in phosphors and semiconductors, whereby charge carriers recombine without releasing photons.

Optoelectronics

Optoelectronics is the study and application of electronic devices and systems that source, detect and control light, usually considered a sub-field of photonics.

Photon

The photon is a type of elementary particle, the quantum of the electromagnetic field including electromagnetic radiation such as light, and the force carrier for the electromagnetic force (even when static via virtual particles).

Quantum efficiency

The term quantum efficiency (QE) may apply to incident photon to converted electron (IPCE) ratio, of a photosensitive device or it may refer to the TMR effect of a Magnetic Tunnel Junction.

Semiconductor

A semiconductor material has an electrical conductivity value falling between that of a conductor – such as copper, gold etc.

Valence and conduction bands

In solid-state physics, the valence band and conduction band are the bands closest to the Fermi level and thus determine the electrical conductivity of the solid.
