Their physical characteristics are determined both by the properties of the host crystal and by the presence of impurities and crystalline defects. Control of these defects determines the commercial ...

These are two-dimensional defects that separate regions of ordered single-crystal structure, crystalline and amorphous regions, or different phases. · A bubble raft model of grain boundaries is shown ...

Using a transmission electron microscope, scientists “dissolved” defects as they formed on the dolomite crystal, speeding up its growth process. Understanding how these minerals form could ...

Dislocations are one-dimensional defects that occur in real crystalline solids and control their plastic deformation. The presence of dislocations permits atomic planes to slip "one atomic row at a ...

We have developed methods for non-contact optical generation of defects in liquid crystals described in our 2010 Nature Materials article by use of optical phase singularities in tightly focused laser ...

Interfaces between the crystalline HEA and amorphous MG plates act as defect sinks, accelerating defect annihilation and minimizing structural damage. Molecular dynamics simulations revealed that ...

Topics covered include: chemical bonding; basic crystallography of crystalline materials; crystal defects; mechanical properties and strength of materials; phase diagrams and transformations; ...

“In solar cells, 1/f noise stems mainly from defects on the surface or interface, such as incomplete lattices, unsaturated dangling bonds, or transmission center capture,” the Chinese group ...
