High-quality bismuth telluride crystals having a thickness of only a few atoms were prepared by a method similar to that for graphene mechanical exfoliation. The potential for these materials to be used as thermoelectric materials was then investigated. It was found that the properties of ...
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 ...
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 ...
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 ...
Thermal conductivity testing was done on nitrogenated ultrananocrystalline diamond films on silicon. Temperature dependence on thermal conductivity was measured using these two techniques. A decrease in thermal conductivity was observed with the introduction of nitrogen addition. It was observed that MCD had the highest thermal ...
