Classes

Antisite Defectc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/AntisiteDefect

Antisite Defect is a point defect which occurs in ordered alloys or compounds when two atoms of different type switch positions.

Point Defect c

Frenkel Defectc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/FrenkelDefect

A Frenkel defect is a point defect which occurs in ionic crystals when an ion is removed to an interstitial position, leaving a vacancy behind.

Point Defect c

Impurityc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/Impurity

An impurity is a point defect where foreign atoms (of different type as the host atom) enter the crystal lattice.

Point Defect c

Interstitial Impurity c, Substitutional Impurity c

Interstitialc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/Interstitial

An interstitial is a point defect where an atom occupies an interstitial site. In crystallography, interstitial sites are the empty space between the atoms (assuming a hard-sphere model).

Interstitial Impurityc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/InterstitialImpurity

A interstitial impurity is a point defect where the atom occupying the interstitial site is of a different type as the matrix.
has super-classes
Impurity c, Interstitial c

Point Defectc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/PointDefect

A point defect is a crystalline defect which is localized at or around a single lattice point. It is considered to be a zero-dimensional defect because it does not extend in any dimension in the lattice.
has sub-classes
Antisite Defect c, Frenkel Defect c, Impurity c, Interstitial c, Schottky Defect c, Vacancy c

Schottky Defectc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/SchottkyDefect

A Schottky defect is a point defect which occurs in ionic crystals when oppositely charged ions create a vacancy in the interior of the lattice and go to the surface.
has super-classes
Point Defect c

Self-interstitialc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/Self-interstitial

A self-interstitial is an insterstitial defect where the atom occupying the interstitial site is of the same type as the matrix.
has super-classes
Interstitial c

Substitutional Impurityc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/SubstitutionalImpurity

A substitutional impurity is an impurity where an atom of different type replaces a host or matrix atom.
has super-classes
Impurity c

Vacancyc back to ToC or Class ToC

IRI: http://purls.helmholtz-metadaten.de/cdos/podo/Vacancy

A vacancy is a point defect in which an atom is missing from its original lattice site.
has super-classes
Point Defect c
