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…
Thermal Resistance at a Twist Boundary and Semicoherent Heterointerface
Ramya Gurunathan, Riley Hanus, Samuel Graham +2
Traditional models of interfacial phonon scattering, including the acoustic mismatch model (AMM) and diffuse mismatch model (DMM), take into account the bulk properties of the mate…
