Modulating the Thermal Conductivity in Hexagonal Boron Nitride

Hexagonal boron nitride (h-BN) is a technologically important layered material used as a dielectric spacer, encapsulant, ultraviolet laser emitter, and hyperbolic material in electronic and photonic applications1,2,3. More recently, h-BN has attracted attention for thermal management of electronics as theoretical calculations4predicted an

ARPA-E Projects to Develop New Technologies for High Performance Heat Exchangers, Components

The U.S. Department of Energy has announced $36 million in awards for 18 projects as part of the High Intensity Thermal Exchange through Materials and Manufacturing Processes (HITEMMP) program, as well as the final OPEN+ Cohort, High Temperature Devices. These project teams seek

Design and Validation of Multilayered Thermal Emitter Using Machine Learning

Scientists designed a multilayered metamaterial that realizes ultra-narrowband wavelength-selective thermal emission by combining the machine learning (Bayesian optimization) and thermal emission properties calculations (electromagnetic calculation). The joint team then experimentally fabricated the designed metamaterial and verified the performance. These results may facilitate
