Thermal boundary conductance and phonon transmission in hexagonal boron nitride/graphene heterostructures
David B. Brown, Thomas L. Bougher, Xiang Zhang +3
Increased power density in modern microelectronics has led to thermal management challenges which can cause degradation in performance and reliability. In many high-power electroni…
Direct Visualization of Thermal Conductivity Suppression Due to Enhanced Phonon Scattering Near Individual Grain Boundaries
Aditya Sood, Ramez Cheaito, Tingyu Bai +9
Understanding the impact of lattice imperfections on nanoscale thermal transport is crucial for diverse applications ranging from thermal management to energy conversion. Grain bou…
Thermal Rectification in CVD Diamond Membranes Driven by Gradient Grain Structure
Zhe Cheng, Brian M. Foley, Thomas Bougher +3
As one of the basic components of phononics, thermal diodes transmit heat current asymmetrically similar to electronic rectifiers and diodes in microelectronics. Heat can be conduc…
Probing Growth-Induced Anisotropic Thermal Transport in CVD Diamond Membranes by Multi-frequency and Multi-spot-size Time-Domain Thermoreflectance
Zhe Cheng, Thomas Bougher, Tingyu Bai +7
The maximum output power of GaN-based high-electron mobility transistors is limited by high channel temperature induced by localized self-heating which degrades device performance…
