Realization of Phonon FETs in 2D material through Engineered Acoustic Mismatch
H. F. Feng, Z. Y. Xu, B. Liu +1
Field-effect transistors (FETs) predominantly utilize electrons for signal processing in modern electronics. In contrast, phonon-based field-effect transistors (PFETs)-which employ…
High-Efficiency Electrically Switchable Nonvolatile Thermal Transistor with Multiple Thermal Conductivity States Based on Ferroelectric HfO2
Yong-Kun Huo, Hui-Feng Feng, Chao Yao +2
While nanoscale electronic logic circuits are well-established, the development of na-noscale thermal logic circuits has been slow, mainly due to the absence of efficient and contr…
Unusually Strong Four-Phonon Scattering Effects on Low-Temperature Thermal Conductivity in Two-Dimensional Materials
H. F. Feng, B. Liu, Xin-Gao Gong +1
First principles-based predictions of lattice thermal conductivity (TC) from perturbation theory have achieved significant success. Usually, it only included three-phonon (3ph) sca…
High-Performance Nonvolatile Spin FETs from 2D Metallic Ferromagnetic and Ferroelectric Multiferroic Heterostructure
B. Liu, X. Zhang, W. Hou +3
All-electric-controlled nonvolatile spin field-effect transistors (SFETs) based on two-dimensional (2D) multiferroic van der Waals (vdW) heterostructures hold great promise for adv…
