Example types with exciton
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
In periodic lattices, the properties of an exciton show momentum (k-vector) dependence. (13 words)
In simpler terms, this means a local deformation of the crystal lattice around the exciton. (15 words)
Small effective mass of electrons that is typical of semiconductors also favors large exciton radii. (15 words)
The recombination of the electron and hole, i.e. the decay of the exciton, is limited by resonance stabilization due to the overlap of the electron and hole wave functions, resulting in an extended lifetime for the exciton. (38 words)
Exciton condensates have been seen in a double quantum well systems. citation Spatially Direct and Indirect Excitons Normally, excitons in a semiconductor have a very short lifetime due to the close proximity of the electron and hole. (37 words)
While energy in optoelectronic devices is often considered in terms of positive and negative charges, opposite charges can also come together and temporarily form an energetic state called an exciton before releasing their energy. (34 words)
Example sentences (16)
Indeed, its spatial scale is about where is effective mass of the exciton, is the exciton-phonon coupling constant, and is the characteristic frequency of optical phonons.
The recombination of the electron and hole, i.e. the decay of the exciton, is limited by resonance stabilization due to the overlap of the electron and hole wave functions, resulting in an extended lifetime for the exciton.
Transforming a free exciton state into a self-trapped one proceeds as a collective tunneling of coupled exciton-lattice system (an instanton ).
While energy in optoelectronic devices is often considered in terms of positive and negative charges, opposite charges can also come together and temporarily form an energetic state called an exciton before releasing their energy.
Because the high-energy electron has a negative charge and the hole has positive charge, the duo remain bound -- forming an exciton.
An applied electric field causes electrons and holes to move into the quantum dot layer and recombine forming an exciton that excites a QD.
Exciton condensates have been seen in a double quantum well systems. citation Spatially Direct and Indirect Excitons Normally, excitons in a semiconductor have a very short lifetime due to the close proximity of the electron and hole.
Fast optical exciton creation was used to form condensates in sub-Kelvin Cu 2 O in 2005 on.
First, self-trapped exciton states are always of a small radius, of the order of lattice constant, due to their electric neutrality.
In periodic lattices, the properties of an exciton show momentum (k-vector) dependence.
In simpler terms, this means a local deformation of the crystal lattice around the exciton.
Small effective mass of electrons that is typical of semiconductors also favors large exciton radii.
The exciton is regarded as an elementary excitation of condensed matter that can transport energy without transporting net electric charge.
The existence of exciton states may be inferred from the absorption of light associated with their excitation.
The hallmark of molecular excitons in organic molecular crystals are doublets and/or triplets of exciton absorption bands strongly polarized along crystallographic axes.
The result is a Wannier exciton, citation which has a radius larger than the lattice spacing.
