Si-Sb-Te (SST) system materials were investigated for non-volatile phase change memory application. By contrast to the conventional GST films, the SST films exhibit stronger thermal stability and ...smaller RESET current, which were resulted from the self-confine and self-heat mechanisms by the amorphous Si-rich regions surrounding the phase change crystalline in SST. It shows a good promise for non-volatile memory applications.
The realization of an EOM VCSEL for high-speed applications is shown. An in-depth device characterization is presented along with the growth and optimization challenges encountered for this ...∼\documentclass12pt{minimal}

\begin{document}$$\sim $$\end{document} 400 layer dual cavity design. Modeling and measurements reveal existing prototype limitations and predict an intrinsic bandwidth potential of 56 GHz for future devices.
The effect of constraints on the measurement electromechanical coupling from polymer films is quantified. This information is essential to the application of electrostrictive materials. Theoretical ...analyses are shown to be in good accord with the experimental results.
A methodology for estimating the shear strength parameters of coarse granular material by means of conventional testing equipment, avoiding the oversized particles and using the finer part of the ...original soil, is investigated. The procedure uses soil samples with a parallel gradation and a maximum particle size compatible with the available testing facilities. Experimental results obtained for five different coarse granular materials are presented, showing the feasibility of the application of this method.
The analysis of earthquake-induced ground settlement is based on study of soil permanent strain under ground motion. So far, some experiential formulas have been established to estimate the permanent ...strain of soils. But the parameters of the established experiential formulas are too much and a lot of tests must be done to determine these parameters. A series of permanent deformation of Nanjing recently deposited muddy soil under cyclic load were completed by WFI cyclic triaxial apparatus and the soil permanent strain experiential formula with three parameters is given. The experimental results show that the permanent strain of Nanjing recently deposited muddy soil increased suddenly when permanent strain is over 4%. So, the permanent strain value 4% may be as the failure standard of soil element under cyclic load. The relationship of axial cyclic stress amplitude and cyclic number under different confining pressure and consolidation ratios in the system of double logarithm coordinates could be normalized by dynamic shear stress ratio based on the concept of maximum cyclic shear plane. So permanent strain parameters of Nanjing recently deposited muddy soil can be determined by test under one confining pressure and consolidation ratio. The soil permanent strain experiential formula with three parameters could predict the earthquake-induced ground settlement of Nanjing recently deposited muddy soil. For application purposes, the permanent strain parameters of Nanjing recently deposited muddy soil are given under cyclic load.
Optical investigations have been carried out on InGaN quantum dots (QDs), with and without a GaN capping layer, showing a massive difference in terms of photoluminescence (PL) emission energy and ...intensity. A large difference has also been observed in excitation power dependent PL spectra. All these differences can be attributed to the existence of the strong quantum confined Stark effect (QCSE) in the QDs with the capping layer. A numerical calculation based on the QCSE model has been made, showing a good agreement with the PL data.
