A Phase-Change Model with a Zone of Coexistence of Phases
IMA Journal of Applied Mathematics, 1988A mathematical model for change of phase is presented, accounting for the presence of regions in which liquid and solid coexist. The basic variables are temperature θ and solid fraction v . We start from a relationship of the type θ = θ ( v ), supposed valid in thermodynamical equilibrium.

ACM Computing Surveys, 2013
This article surveys the current state of phase-change memory (PCM) as a nonvolatile memory technology set to replace flash and DRAM in modern computerized systems. It has been researched and developed in the last decade, with researchers providing better architectural designs which address the technology's main challenges—its limited write endurance ...

Multilevel phase-change memory
2010 17th IEEE International Conference on Electronics, Circuits and Systems, 2010Phase-change memory (PCM) has emerged in recent years as one among the most attractive technologies for future non-volatile solid-state memory. PCM relies on the reversible phase transition in chalcogenide materials between different states, i.e., amorphous and poly-crystalline, which are characterized by very different electrical properties ...

Phases and Phase Changes of Clusters
1996Phase-like forms are expected to be observable for many kinds of clusters, insofar as they should satisfy criteria used to characterize phases of bulk form. However clusters are also expected to exhibit phase-like forms that do not have direct counterparts in bulk matter, and the equilibrium and transformations among these forms can be quite different ...

Interfacial phase-change memory
Nature Nanotechnology, 2011Phase-change memory technology relies on the electrical and optical properties of certain materials changing substantially when the atomic structure of the material is altered by heating or some other excitation process. For example, switching the composite Ge(2)Sb(2)Te(5) (GST) alloy from its covalently bonded amorphous phase to its resonantly bonded ...

Slope Effect of Phase Change Materials in Phase Change Roof
Advanced Materials Research, 2013Under summer climatic features of Daqing area in China, numerical simulation on the unsteady heat transfer characteristic of phase change roof was investigated, considering direct influence of solar radiation. The main influencing factor of roof slope in the phase change roof was analyzed in this paper.

19th International Conference on VLSI Design held jointly with 5th International Conference on Embedded Systems Design (VLSID'06), 2006
Chalcogenide based phase change memory (PCM) is a promising type of non-volatile memory that possibly replace the currently wide spread flash memory. Current research on PCMs targets the integration, feasibility, and reliability of such memory technology into the widely used CMOS process technology.

Phase Changes in the Upper Mantle
Science, 1967The C-region of the upper mantle has two transition regions 75 to 90 kilometers thick. In western North America these start at depths of 365 kilometers and 620 kilometers and involve velocity increases of about 9 to 10 percent. The locations of these transition regions, their general shape, and their thicknesses are consistent with, first, the ...
