Sentence examples for reduced dislocation density from inspiring English sources

There is an urgent need for developing new approaches to further improve material quality with reduced dislocation density and unintentional impurities and improved surface morphologies in Al-rich AlGaN alloys, which would enhance the doping efficiency and device performance.

Increasing the thickness to 100 nm resulted in complete island coalescence, formation of undulating films from the polishing scratches in the SiC substrate, a surface microstructure containing steps, terraces and small pits, and a reduced dislocation density relative to the 15 nm layers.

On the other hand, the dislocation density decreases considerably in the corresponding temperature regime, yielding grains of small size (∼30 nm) that have sharp boundaries and a reduced dislocation density.

Both the shrinkage and annihilation of dislocations resulted in reduced dislocation density (see the dips in Fig. 12b and c).

This process exhausts nucleated dislocations in nanosphere and reduces dislocation density, corresponding to the dislocation starvation mechanism.

They also found that these CrN nanoislands can mask the dislocation propagation and thus reduce dislocation density of the GaN films effectively.

However, the efficient strategy to reduce dislocation density is to initiate annihilation and fusion reaction among them during their glide process.

The ex situ RPD AlN nucleation layer can significantly reduce dislocation density and thus improve the crystal quality of the GaN epitaxial layers.

An alternative technology for effectively reducing dislocation density is a kind of selective epitaxial growth on patterned Si substrate, which has the capability to produce a low-threading-dislocation surface using a simple epitaxial growth process.

The interaction of dislocations with such embedded particles has been assessed and critical remarks are given as to the use of this technique in order to reduce dislocation densities in synthetic diamond.

This bone-conserving procedure [7, 8] with additional advantages of easier revision [9, 10], preservation of proximal femoral bone density [11], reduced dislocation rates [2, 3], and more precise biomechanical reconstruction [12] holds promise as a viable alternative to total hip arthroplasty, especially in young, active individuals who are likely to outlive a primary hip arthroplasty.
