摘要:
AbstractAt temperatures above the brittle‐to‐ductile transition (490 °C) in Te‐doped GaAs three types of predominant defect configurations have been observed after uniaxial compression along a [001] direction: (i) twins and stacking faults (500 … 520 °C), (ii) slip zones of dislocations (≈ 550 °C) and (iii) dislocation cells (580 … 590 °C). In Part I quantitative details of the appearance of twins and stacking faults are given. Most frequently found were 30° partials in twins and

摘要:
AbstractLattice strains have been produced in cadmium telluride by grinding for different durations. X‐ray diffractograms have been obtained at different stages of grinding. The lattice constants, particle size, lattice strain and Debye‐Waller factors have been determined. From the correlation between the strain and the effective Debye‐Waller factor, the Debye‐Waller factor for zero strain has been es

摘要:
AbstractEffects of varying the composite heterostructure geometry have been investigated in the context of InGaAsP/InP (λ λ= 1.3 μm) non‐coherent radiation sources. The study has been guided by a preliminary theoretical analysis and complemented by evaluation of the statistics in sample ensembles. Optimum construction diodes emit 600–700 μW/facet of optical power. The added quaternary layer of intermediate bandgap (Λgλ= 1.1 μm) has been found to have benefical effect on the quantum efficiency and reproducibility of the manufacturi

摘要:
AbstractSilicalite‐1, the aluminum‐free end number of the ZSM‐5 zeolites, was synthesized from a batch composition of 3.25 Na2O · 40.0 SiO2· 552 H2O · 2.00 TPA by using tetrapropylammonium bromide (TPA‐Br) or chloride (TPA‐Cl) as templates in the temperature range of 100 to 175 °C in a batch system. Conversion of silica in the starting batch composition into silicalite‐1 in the product was followed quantitatively. The activation energies of nucleation and crystallization were determined as 37.2 and 66.5 kJ/mol, respectively. The use of TPA‐Cl as the template instead of TPA‐Br results in longer induction period for crystallization to start and a larger crys
