3D printing strategies provide flexible solutions for complex and programmable thermal management versatile material integration. 3D-printed composite phase change materials (PCMs) can overcome shape limitations optimize structures to construct object designs effective management. Recently in Matter, Emily B. Pentzer et al. creatively proposed a facile strategy print PCM-filled inks with excell...

Phase change memory uses brief pulses of electrical current to induce phase transitions in chalcogenide material regions with dimensions near or even far below 50 nm. The strongly differing electrical conductivities of the crystalline and amorphous phases allow data storage at densities in excess of terabits per square inch. Nanoscale conduction heat transfer governs the figures of merit in the...

The thermal response characteristic of a hybrid cooler that is charged with a “dry” solid-solid phase change compound is evaluated. A mathematical model that simulates the performance of a cooler/heat storage unit is formulated. A prototype heat sink that incorporates heat storage using a “dry” PCM is tested, and used to benchmark the simulation model. Different heating and cooling strategies a...

We demonstrate the formation of confinement potentials in suspended nanostructures induced by the geometry of the devices. We then propose a setup for measuring the resulting geometric phase change of electronic wave functions in such a mechanical nanostructure. The device consists of a suspended loop through which a phase coherent current is driven. Combination of two and more geometrically in...

Phase change memory (PCM) has opportunities of various applications on the premise of its high performance operations, which are still to develop with innovations such as change of a memorymaterial. In respects of high-speed and high-scalability memory characteristics, d-phase Ge-doped SbTe (GeST) materials stand as highly promising candidates. An overview of the material and device characteris...

Phase change memory (PCM), which exploits the phase change behavior of chalcogenide materials, affords tremendous advantages over conventional solid-state memory due to its nonvolatility, high speed, and scalability. However, high power consumption of PCM poses a critical challenge and has been the most significant obstacle to its widespread commercialization. Here, we present a novel approach ...

A reflective-type display device based on phase change materials is attractive because of its ultrafast response time and high resolution compared with a conventional display device. This paper proposes and demonstrates a unique display device in which multicolour changing can be achieved on a single device by the selective crystallization of double layer phase change materials. The optical con...

The macroscopic model of solid-solid phase change presented makes use of internal variables to represent the phase fractions and the local strains. As such, it can be cast in the framework of standard materials with internal constraints. These constraints are accounted for by Lagrange's multipliers. Reversible or irreversible phase changes are considered in a general way. Material stability is ...
