High Thermal Conductivity in Wafer Scale Cubic Silicon Carbide Crystals
Zhe Cheng, Jianbo Liang, Keisuke Kawamura +7
High thermal conductivity electronic materials are critical components for high-performance electronic and photonic devices as either active functional materials or thermal managem…
Measurements and Numerical Calculations of Thermal Conductivity to Evaluate the Quality of β-Gallium Oxide Thin Films Grown on Sapphire and Silicon Carbide by Molecular Beam Epitaxy
Diego Vaca, Matthew Barry, Luke Yates +8
We report a method to obtain insights into lower thermal conductivity of β-Ga2O3 thin films grown by molecular beam epitaxy (MBE) on c-plane sapphire and 4H-SiC substrates. We comp…
Experimental Observation of Localized Interfacial Phonon Modes
Zhe Cheng, Ruiyang Li, Xingxu Yan +12
Interfaces impede heat flow in micro/nanostructured systems. Conventional theories for interfacial thermal transport were derived based on bulk phonon properties of the materials m…
Thermal Visualization of Buried Interfaces by Transient and Steady-State Responses of Time-Domain Thermoreflectance
Zhe Cheng, Fengwen Mu, Xiaoyang Ji +6
Thermal resistances from interfaces impede heat dissipation in micro/nanoscale electronics, especially for high-power electronics. Despite the growing importance of understanding i…
Phonon heat conduction in Al1-xScxN thin films
Chao Yuan, Mingyo Park, Yue Zheng +4
Aluminum scandium nitride alloy (Al1-xScxN) is regarded as a promising material for high-performance acoustic devices used in wireless communication systems. Phonon scattering and…
Quasi-Ballistic Thermal Conduction in 6H-SiC
Zhe Cheng, Weifang Lu, Jingjing Shi +9
The minimization of electronics makes heat dissipation of related devices an increasing challenge. When the size of materials is smaller than the phonon mean free paths, phonons tr…
