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°C. Highly controlled growth conditions for the diamond ensured that it was of good quality. Thermal conductivity measurements using the laser flash method were performed ...
Li-ion battery electrodes are typically mixed with carbon black materials which have low thermal conductivity in high-power-density battery applications. In this study, multi-walled carbon nanotubes (MWCNTs) were added to Li-ion battery electrodes to improve thermal conductivity. A measured the thermal conductivity of the electrode samples at room temperature using the transient plane source (TPS) method. Results showed that the addition of MWCNTs ...
