High-pressure phase transitions in Zn 1 − x M x Se ( M = Cd , Fe, and Mn)

Abstract: Energy-dispersive x-ray diffraction was employed to study pressure-induced phase transitions in ${\mathrm{Zn}}_{0.84}{\mathrm{Fe}}_{0.16}$Se, ${\mathrm{Zn}}_{0.9}{\mathrm{Cd}}_{0.1}$Se, and ${\mathrm{Zn}}_{0.76}{\mathrm{Mn}}_{0.24}$Se crystals up to 21.0, 23.3, and 24.3 GPa, respectively. Our result shows that the $B3$ to $B1$ structure transitions for these crystals occurred at 11.4$\ifmmode\pm\else\textpm\fi{}$0.5, 9.5$\ifmmode\pm\else\textpm\fi{}$0.3, and 9.6$\ifmmode\pm\else\textpm\fi{}$0.5 GPa, respectively. Compared to the phase-transition pressure ${(P}_{t})$ of ZnSe (14.4 GPa), a reduction of about 3--5 GPa is exhibited in these ternary compounds. This reduction in phase-transition pressure $\ensuremath{\Delta}{P}_{t}$ in the ternary compounds suggests that the fractional volume change, $(\ensuremath{\Delta}{V/V}_{0})$, of the $B3\ensuremath{-}B1$ phase admixture might be the source of this reduction. Our results indicate that ${P}_{t}$ (with respect to the phase transition pressure 14.4 GPa of ZnSe) is related to the fractional volume change $(\ensuremath{\Delta}{V/V}_{0})$ by the expression ${P}_{t}$=[14.4003+0.1568$(\ensuremath{\Delta}{V/V}_{0})$-0.0281$(\ensuremath{\Delta}{V/V}_{0}{)}^{2}$] GPa.

Measuring business performance in the high-tech manufacturing industry: A case study of Taiwan's large-sized TFT-LCD panel companies

Abstract: The nature of competition in the high-technology manufacturing industry has changed dramatically over the last two decades, and any of the traditional indicators of business performance are insufficient today. We have identified a new set of financial and non-financial performance indicators that can be used by high-tech manufacturing companies and have developed a business performance evaluation model. A data envelopment analysis (DEA), an analytic hierarchy process (AHP), and a fuzzy multi-criteria decision-making approach are used in the model. Data from large-sized thin-film transistor liquid-crystal display panel companies in Taiwan were collected via a field survey and from various published databases and were fed into the model to determine the relative business performance of the companies. We hope that our findings will help high-tech manufacturing executives determine their companies’ strengths and weaknesses and lead to future improvements in business operations.
