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…
Thermal boundary conductance across epitaxial ZnO/GaN interfaces: Assessment of phonon gas models and atomistic Green's function approaches for predicting interfacial phonon transport
John T. Gaskins, George Kotsonis, Ashutosh Giri +13
We present experimental measurements of the thermal boundary conductance (TBC) from K across isolated heteroepitaxially grown ZnO films on GaN substrates. These data pro…
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…
