Achieving Minimal Heat Conductivity by Ballistic Confinement in Phononic Metalattices
Weinan Chen, Disha Talreja, Devon Eichfeld +14
Controlling the thermal conductivity of semiconductors is of practical interest in optimizing the performance of thermoelectric and phononic devices. The insertion of inclusions of…
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…
Titanium Contacts to Graphene: Process-Induced Variability in Electronic and Thermal Transport
Keren M. Freedy, Ashutosh Giri, Brian M. Foley +3
Contact Resistance (RC) is a major limiting factor in the performance of graphene devices. RC is sensitive to the quality of the interface and the composition of the contact, which…
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…
