Designing 1D correlated-electron states by non-Euclidean topography of 2D monolayers
Sunny Gupta, Henry Yu, Boris I. Yakobson
Two-dimensional (2D) bilayers, twisted to particular angles to display electronic flat bands, are being extensively explored for physics of strongly correlated 2D systems. However,…
Step-edge epitaxy for borophene growth on insulators
Qiyuan Ruan, Luqing Wang, Ksenia V. Bets +1
Borophene, a monoatomic layer of boron atoms, stands out among two-dimensional (2D) materials, with its versatile properties of polymorphism, metallicity, plasmonics, superconducti…
Stability and electronic properties of two-dimensional gallium
Alex Kutana, Qiyuan Ruan, Jun-Jie Zhang +2
Two-dimensional metals offer intriguing possibilities to explore metallicity and other related properties in systems with reduced dimensionality. Here, following recent experimenta…
Single-crystal hexagonal boron nitride monolayer epitaxially grown on Cu (111) thin film across a wafer
Tse-An Chen, Chih-Piao Chuu, Chien-Chih Tseng +9
We demonstrate single crystal growth of wafer-scale hexagonal boron nitride (hBN), an insulating atomic thin monolayer, on high-symmetry index surface plane Cu(111). The unidirecti…
