Crystallographic defect
WebLine defects, or dislocations, are lines along which whole rows of atoms in a solid are arranged anomalously. The resulting irregularity in spacing is most severe along a line called the line of dislocation. Line defects can weaken or strengthen solids. …a dislocation, which is a line defect that may run the length of the crystal. WebOct 1, 2024 · Defects (bulk and interface) are recombination sites which reduce the VOC, JSC, and FF of solar cells [ 21]. The carrier transport and defect properties of devices are influenced by the grain orientation of the absorber layer for this particular material, which is crucial for device performance [22 ].

WebA micropipe, also called a micropore, microtube, capillary defect or pinhole defect, is a crystallographic defect in a single crystal substrate. Minimizing the presence of micropipes is important in semiconductor manufacturing, as their presence on a wafer can result in the failure of integrated circuits made from that wafer. WebIn a real lattice, a crystallographic defect is a deviation from the ideal lattice at a given lattice position and thus defects can be defined as “defect” = “real-ideal” with respect to charge and element. This definition is used in the Kröger-Vink notation to …
