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 ...
This study aimed to develop a new technique for thermal management in high powered gallium nitride (GaN) electronic and optoelectronic devices. The researchers integrated GaN with diamond through the process of depositing high-quality nanocrystalline diamond films directly onto the GaN material at temperatures between 450-500°...
Using few-layer graphene (FLG) flakes the authors are able to create graphene composites (where graphene is a filler) and measure the thermal properties of these composites using a laser flash technique. In some cases, the thermal conductivity was increased by ten times while only using 5 ...
As electronic devices become smaller, power densities increase and so do hotspot temperatures, leading to a need for materials that can exchange heat better. The materials that facilitate this heat exchange are called thermal interface materials (TIMs). Graphene has been shown to demonstrate superior thermal ...
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 ...
