Tunable Thermal Conductivity of Two-Dimensional SiC Nanosheets by Grain Boundaries: Implications for the Thermo-Mechanical Sensor

“…These nanocrystals have demonstrated excellent electrocatalytic activity in the hydrogen evolution reaction, comparable to commercial Pt electrodes. , The study found that natural defects and external impurities have a significant impact on the performance of SiC, with the presence of defects significantly reducing the overall carrier mobility of SiC. The effects on mechanical and electrical properties are also widespread. , In terms of thermal management, the thermal transport properties can be effectively controlled through temperature, external strain, and magnetic. − During the experimental preparation process, the influence of grain boundary angles, strains, and defects often occurs. Although our previous research has provided valuable insights into the thermal properties of SiC, there is still a lack of comprehensive understanding regarding the combined effects of these factors, especially considering the dual interfaces formed by different bonding types in the SiC GB structure and the application of strain engineering on the SiC GB structure.…”
