Monolithic integration of diverse crystalline thin films on diamond for near-junction thermal management
Tiancheng Zhao, Tianqi Bai, Yang He +20
The pursuit of extreme miniaturization and high power in 6G RF front-ends has cast thermal dissipation as the central challenge. Here, we have demonstrated the monolithic integrati…
Interface phonon modes governing the ideal limit of thermal transport across diamond/cubic boron nitride interfaces
Xiaonan Wang, Xin Wu, Penghua Ying +2
Understanding the ideal limit of interfacial thermal conductance (ITC) across semiconductor heterointerfaces is crucial for optimizing heat dissipation in practical applications. B…
Dissimilar thermal transport properties in -GaO and -GaO revealed by machine-learning homogeneous nonequilibrium molecular dynamics simulations
Xiaonan Wang, Jinfeng Yang, Penghua Ying +3
The lattice thermal conductivity (LTC) of GaO is an important property due to the challenge in the thermal management of high-power devices. We develop machine-learned neur…
Hidden phase uncovered by ultrafast carrier dynamics in thin Bi2O2Se
Hao Li, Adeela Nairan, Xiaoran Niu +8
Bi2O2Se has attracted intensive attention due to its potential in electronics, optoelectronics, as well as ferroelectric applications. Despite that, there have only been a handful…
