Thermal Conductance across beta-Ga2O3-diamond Van der Waals Heterogeneous Interfaces
Zhe Cheng, Luke Yates, Jingjing Shi +3
Because of its ultrawide bandgap, high breakdown electric field, and large area affordable substrates grown from the melt, beta Ga2O3 has attracted great attention recently for pot…
Tunable Thermal Energy Transport across Diamond Membranes and Diamond-Si Interfaces by Nanoscale Graphoepitaxy
Zhe Cheng, Tingyu Bai, Jingjing Shi +14
The development of electronic devices, especially those that involve heterogeneous integration of materials, has led to increased challenges in addressing their thermal operational…
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…
