Despite the difficulty in visualization, the stresses caused by a screw dislocation are less complex than those of an edge dislocation.
12.
This means edge dislocations move in directions parallel to their dislocation lines and screw dislocations move in directions perpendicular to their dislocation lines.
13.
For example, there are compressively strained bonds directly next to an edge dislocation and tensilely strained bonds beyond the end of an edge dislocation.

HIRF can be improved by incorporating dopants that create temporary deep electron traps, optimizing the degree of sulfur sensitization, introducing crystalline defects ( edge dislocation ).
16.
This is very often the site of shallow electron traps, such as crystalline defect ( particularly edge dislocation ) and silver sulfide specks created by sulfur sensitization process.
17.
Edge dislocations have the direction of the burgers vector perpendicular to the dislocation line, while screw dislocations have the direction of the burgers vector parallel to the dislocation line.
18.
Shallow electron traps are created by sulfur sensitization, introduction of a crystalline defect ( edge dislocation ), and incorporating a trace amount of non-silver salt as a dopant.
19.
Many modern negative emulsions introduce a layer just under the crystal surface where a sufficient number of edge dislocations are intentionally created, while maintaining the bulk of the crystal interior defect-free.
20.
Most, if not all, old technology negative film emulsions had many unintentionally created edge dislocation sites ( and other crystalline defects ) internally and sulfur sensitization was performed on the surface of the crystal.
