CHE SIGNIFICA POINT DEFECT IN INGLESE
Difetto cristallografico
I solidi cristallini presentano una struttura cristallina periodica. Le posizioni di atomi o molecole si verificano ripetendo distanze fisse, determinate dai parametri delle cellule unità. Tuttavia, la disposizione di atomi o molecole nella maggior parte dei materiali cristallini non è perfetta. I modelli regolari sono interrotti da difetti cristallografici.
definizione di point defect nel dizionario inglese
La definizione di difetto puntuale nel dizionario è un'imperfezione in un cristallo, caratterizzata da una posizione del reticolo non occupato o da un atomo, molecola o ione interstiziale.

The Physics of Semiconductors: An Introduction Including ...
At thermodynamical equilibrium a (point) defect density ∝ exp ( −GfD/kT ) will
always be present (cf. Sect. 4.2.2). Point defects (Sect. 4.2) are deviations from
the ideal structure involving essentially only one lattice point. The formation
energy ...

Point Defects in Semiconductors and Insulators: ...
An obvious meaning of the word structure is the atomic configuration of a point
defect. Generally, a point defect is a defect with "zero dimension" on a
macroscopic scale, in contrast to defects with "one dimension", such as
dislocations, or "two ...

Introduction to Liquid Crystals: Chemistry and Physics
In the nematic phase, the alignment of the molecules can often converge to a
point (a point defect). The molecules can align in this manner in a number of
different ways; some of these alignments are shown in Figure 9.4 (a-d). In the first

Crystallography and Crystal Defects
A point defect differs from a dislocation and from a two-dimensional defect such
as a crystal boundary in two important respects. The first is that it is difficult to
observe directly, so that in the main it can be detected and studied only through
its ...

An Introduction to Mineral Sciences
Another possible type of point defect occurs when an atom moves from a site,
leaving a vacancy, and is placed in an alternative interstitial site which is
normally unoccupied. This is a Frenkel defect and again leaves the overall

Dislocations in Solids
Simulating the point defect by an array of point forces reveals the form of the
lattice contribution arising from the discrete atomic arrangement around the
defect. While this term is unimportant at large distances from the dislocation, it
becomes ...
