Understanding High-Field Electron Transport Properties of Monolayer Transition Metal Dichalcogenides and Strain Effects
Chenmu Zhang, Long Cheng, Yuanyue Liu
Monolayer transition metal dichalcogenides (MX2) are promising candidates for future electronics. Although the transport properties (e.g. mobility) at low electric field have been…
Why Two-Dimensional Semiconductors Generally Have Low Electron Mobility
Long Cheng, Chenmu Zhang, Yuanyue Liu
Atomically thin (two-dimensional, 2D) semiconductors have shown great potential as the fundamental building blocks for next-generation electronics. However, all the 2D semiconducto…
Enhancing Interconnect Reliability and Performance by Converting Tantalum to 2D Layered Tantalum Sulfide at Low Temperature
Chun-Li Lo, Massimo Catalano, Ava Khosravi +9
The interconnect half-pitch size will reach ~20 nm in the coming sub-5 nm technology node. Meanwhile, the TaN/Ta (barrier/liner) bilayer stack has to be > 4 nm to ensure acceptable…
Two-dimensional Halide Perovskites: Tuning Electronic Activities of Defects
Yuanyue Liu, Hai Xiao, William A. Goddard
Two-dimensional (2D) halide perovskites are emerging as promising candidates for nano-electronics and optoelectronics. To realize their full potential, it is important to understan…
Origin of low sodium capacity in graphite and generally weak substrate binding of Na and Mg among alkali and alkaline earth metals
Yuanyue Liu, Boris V. Merinov, William A. Goddard
It is well known that graphite has a low capacity for Na but a high capacity for other alkali metals. The growing interest in alternative cation batteries beyond Li makes it partic…
Dislocations and Grain Boundaries in Two-Dimensional Boron Nitride
Yuanyue Liu, Xiaolong Zou, Boris I. Yakobson
A new dislocation structure-square-octagon pair (4|8) is discovered in two-dimensional boron nitride (h-BN), via first-principles calculations. It has lower energy than correspondi…
