Adatom-induced dislocation annihilation in epitaxial silicene
Antoine Fleurence, Yukiko Yamada-Takamura
The transformation of the stripe domain structure of spontaneously-formed epitaxial silicene on ZrB thin film into a single-domain driven by the adsorption of a fraction of a m…
First-principles study on the stability and electronic structure of monolayer GaSe with trigonal-antiprismatic structure
Hirokazu Nitta, Takahiro Yonezawa, Antoine Fleurence +2
The structural stability and electronic states of GaSe monolayer with trigonal-antiprismatic (AP) structure, which is a recently discovered new polymorph, were studied by first-pri…
Bandgap engineering in an epitaxial two-dimensional honeycomb SiGe alloy
Antoine Fleurence, Yuto Awatani, Camille Huet +4
In this Letter, we demonstrate that it is possible to form a two-dimensional (2D) silicene-like SiGe compound by replacing the Si atoms occupying on-top sites in the planar-lik…
Hidden mechanism for embedding the flat bands of Lieb, kagome, and checkerboard lattices in other structures
Chi-Cheng Lee, Antoine Fleurence, Yukiko Yamada-Takamura +1
The interplay of hopping parameters that can give rise to flat bands in consequence of quantum interference in electronic, photonic, and other interesting materials has become an e…
