Properties of graphene produced by the high pressure-high temperature growth process

In this article, the authors present a novel method for the synthesis of graphene layers that can be used in advanced electronic devices, among other applications. The preparation method involves the use of a high-pressure high-temperature process where the pressure and temperature are closely monitored in order to preferentially prepare graphene layers. The quality of the material synthesized is much better than previously reported, and the size of the layers ...

Thermal properties of the optically transparent pore-free nanostructured yttria-stabilized zirconia

Yttria-stabilized zirconia (YSZ) was synthesized by the spark plasma sintering process to generate pore-free, homogenous bulk samples that were then tested for thermal conductivity, which was measured by two separate methods: TPS and LFT. The TPS method was found to be better for measuring of thermal conductivity in this specific case. Using the phonon-hopping model (PHM) the authors were able to determine how grain boundaries of the bulk samples affected ...

Mechanically-exfoliated stacks of thin films of Bi2Te3 topological insulators with enhanced thermoelectric performance

The 'graphene-like' mechanical exfoliation of Bi2Te3 films is shown to have a significant effect on the thermoelectric properties of these films. The modification of thermal conductivity due to exfoliation leads to enhanced thermoelectric properties, known as figures of merit (ZT).Two different experimental techniques were used in order to determine the thermal conductivity of the exfoliated films: transient plane source (TPS) and laser flash technique (LFT). Annealing was performed ...
