Colors in diamond originate from lattice defects and impurities.
Applications for this method include the identification of lattice defects in crystals.
This transport mode is limited by the elastic scattering of acoustic phonons at lattice defects.
A simple schematic diagram of such atomic planes can be used to illustrate lattice defects such as dislocations.
These materials are always iron-deficient owing to the presence of lattice defects, namely iron vacancies.
Chemically pure calcite may show a blue CL which is probably due to an intrinsic lattice defect.
The yellow color originates from abundant lattice defects (such as oxygen vacancies) and is related to internal transitions at the Ho ions.
Silicon single crystals may be produced today in commercial facilities with extremely high purity with few lattice defects.
The affected area contains a large number of lattice defects, negatively affecting its performance.
Those lattice defects are most likely responsible for the color of the notable diamonds described above.
