Abstract

The preparation of quantum silicon nanowires, materials with potential application in high-performance nanodevices, is challenging. Here, the authors synthesize vertically aligned sub-5 nm silicon nanowires via a vapor phase silicon etching process; the resulting material features unusual lattice reduction and significant phonon and electronic confinement effects.

4. Spatial Control of Substitutional Dopants in Hexagonal Monolayer WS

Author

Tianyi, Zhang, Mingzu, Liu, Kazunori, Fujisawa, Michael, Lucking, Kory, Beach, Fu, Zhang, Maruda, Shanmugasundaram, Andrey, Krayev, William, Murray, Yu, Lei, Zhuohang, Yu, David, Sanchez, Zhiwen, Liu, Humberto, Terrones, Ana Laura, Elías, and Mauricio, Terrones

Abstract

The ability to control the density and spatial distribution of substitutional dopants in semiconductors is crucial for achieving desired physicochemical properties. Substitutional doping with adjustable doping levels has been previously demonstrated in 2D transition metal dichalcogenides (TMDs); however, the spatial control of dopant distribution remains an open field. In this work, edge termination is demonstrated as an important characteristic of 2D TMD monocrystals that affects the distribution of substitutional dopants. Particularly, in chemical vapor deposition (CVD)-grown monolayer WS
