Using MBE(Molecular Beam Epitaxy) technique and SK growth mode, through the stress distribution design of the materials system, controlling the growth dynamics and optimizing growth technologies, the uniformity, the density and the spatial ordering of In(Ga)As/GaAs,InAlAs/AlGaAs/GaAs and InAs/InAl(Ga)As/InP nanostructrues can be experimentally controlled. Free defects of quantum dots and quantum wires have been obtained,which are extremely important for device application in future.
4. Aggregate location conflicting and overlapping criteria in the algorithm were established. Growth pattern and convexity conditions were analyzed for a convex polyhedron aggregate. The 3D-RAS (Three Dimensional Random Aggregate Software) was presented in the paper.
4. 建立了以体积为标度的凸型多面体骨料侵入判别准则,并以体积为研究对象建立了凸型骨料的生长模式和骨料“凸性”条件,研制出了三维任意形状骨料生成软件3D-RAS(THREE DIMENSIONAL RANDOM AGGREGATE SOFTWARE)。
We investigated the chromosomal karyotypes, in vitro CFU-GM growth patterns, proliferating cell nuclear antigen(PCNA) expression, cell cycle kinetics and hematopoiesis clonality of bone marrow cells from 37 MDS patients, two post MDS AML(MDS/AML) patients and 11 normal controls.
There is the same regression equation:V=1.0972g0.9731 between volume and weight during growth and development of Hayward andJinfeng fruits. The result indicates that the growth patterns of these different varieties are the same.
According to the thin film interference principle,detailed elaboration and analysis about the dependences of the oscillation amplitude change of GaN thin film growth interference curve on the thin film growth patterns and the surface roughness through establishing thin film reflection model were made.
The growth mode developed provides growth rates that are five times higher of large high-quality optical KDP crystals.
Control over the parameters of InAs-GaAs quantum dot arrays in the Stranski-Krastanow growth mode
At high indium concentrations, a transition from the two dimensional to island growth mode was observed, which was caused by an increase in the mismatch strain.
With decreasing droplet diameter, the growth mode of the primary phase α changes from faceted to nonfaceted growth and the eutectic changes from needle-like to anomalous eutectic.
The growth mode of (ε + θ + Sb) ternary eutectic exhibits a transition of "divorced eutectic-mixture of anomalous and regular structures-regular eutectic" along the sample axis due to the inhomogeneity of sound field distribution.
The growth pattern of Saccharomyces cerevisiae and Propionibacterium freudenreichii ssp.
Analysis of the growth pattern of stromatolites and relationships of their thick carbonate bodies with host rocks are used to substantiate the lack of reefs sensu stricto, i.e., buildups notably towering above the sea bottom, in the Proterozoic.
Similarly, direct exposure of etiolated pea seedlings to commercial ethylene gas also modified the growth pattern in the same way.
The growth pattern of the Walker 256 solid tumor has been studied in rats with different doses of the mutant vasopressin gene.
Aggravated hypoxia resulted in the accelerated ethylene production and the activation of enzymes destroying cell walls in the adventitious roots; as a result, the latter changed their growth pattern.
