Diffuson-driven Ultralow Thermal Conductivity in Amorphous Nb2O5 Thin Films
Zhe Cheng, Alex Weidenbach, Tianli Feng +9
Niobium pentoxide (Nb2O5) has been extensively reported for applications of electrochemical energy storage, memristors, solar cells, light emitting diodes (LEDs), and electrochromi…
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…
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…
